From what we gathered so far, PA is a common denominator of all binaries that are crashing... this seems to happen since the update to PA 7.0

I'll try to get somebody to attach a backtrace here;

I'm currently sick at home, so cannot debug in details, unfortunately.

Yes, this is the most important piece of information.  Please install debuginfo packages and get the backtrace with symbols.

The bug must have appeared on TW, too.  Coolo mentioned that it appears on openQA (or a typo?).  If this can be reproduced on KVM/QEMU, it'd be great....

Backtrace (provided on IRC, my gdb setup is broken at the moment):

Yes, we have seen amarok crashees and others inside openQA as well.. so it does reproduce in kvm/qemu.

Forgot to mention: yes, since the 1012 snapshot has been released (first to have PA 7.0!) we heard also reports from TW users.

I update me TW install to snapshot 20151012 and bug also reproduced.

The highlight is still hidden here.  Please install all relevant debuginfo packages for PA and get the stack trace.

Ondrej, could you check whether you can reproduce / debug this in your side, too?

I'll try Leap in a moment.
I can't reproduce it using latest TW (20151012) and PA from my home project (but I have no additional patches, source is identical to one in Devel, so I assume the same as in TW). I'll try official TW builds next.
I also didn't notice any threads about crashes in PA ML so far.

I'll ask the person to: unfortunately I can't run gdb here...

PA-knotify crash

I switched to use TW packages and after login-cycle everything is still working. Next I installed Leap (build 235) in qemu-kvm - default Plasma5 installation - and amarok started ok, sound was playing. But then knotify tried to play something and crashed (note that it may be different issue).

I'm attaching trace. From the brief look and going through the code PA I would point to insufficient input validating on PA side, but primarily something from Phonon is not passing correct data. That may explain why I don't see this crashes on my home and work machines as I'm not using default gstreamer backend, but vlc backend.

This looks like a code path related with srb channel, which was enabled as default since 7.0.  Could you try to disable it, e.g. modifying in /etc/pulse/default.pa to replace the line

load-module module-native-protocol-unix

with

load-module module-native-protocol-unix srbchannel=no

confirmed. without that it's crashing every time I log into KDE, with srbchannel=no the crash is gone

and KDE is not the only part that crashes:

Confirm too.

OK, now I'm building a PA package with srbchannel re-disabled in OBS home:tiwai:branches:multimedia:libs/pulseaudio repo.  Please check whether it works for you (don't forget to revert your changes in /etc/pulse before testing).

*** Bug 950622 has been marked as a duplicate of this bug. ***

Now I merged my fix package to OBS multimedia:libs, submitted to both FACTORY and Leap.

I keep this bug open for a while since my fix is really a workaround.  The upstream devs take a look at it, so we may get a better fix.

This is an autogenerated message for OBS integration:
This bug (950487) was mentioned in
https://build.opensuse.org/request/show/339257 Leap:42.1 / pulseaudio

Can anyone test the PA packages in OBS home:tiwai:bnc950487/pulseaudio repo?  This has a debug patch (and the workaround is disabled again).  After installing the packages, reproduce the usual crash, then get a log via

PULSE_LOG=99 pactl info

... which includes the crash.  Please attach the log to Bugzilla.

Hi, I am searching this repo, but the folder bnc950487 do not contain pulseaudio. Where I find it?

Well, pulseaudio is the package repository of that given project.  The download repository is either openSUSE_Factory or openSUSE_Leap_42.1 depending on your system, of course.

Thanks, but where the string 'PULSE_LOG=99 pactl info' to be copied?

You need to open a terminal, and run that command in bash.
Alternatively run like
  export PULSE_LOG=99
  pactl info > pa.info

Created attachment 651967 [details]
Result of PULSE_LOG=99 pactl info

Thanks!  This helped a lot to identify the issue.

Could you try again the package in the same OBS home:tiwai:bnc950487 repo?  Now it's renewed with the fix patch.

If this is confirmed to work, I'll refresh the package and resubmit with the proper fix instead of a workaround.

With this patch now works perfectly in my PC and KDE errors no longer appear.
I hope that at least for this one should not wait for the kernel 4.3 ... ;-)
Thank you!

Great, thanks for a quick test.
Now I submitted the fix package again.  Let's close now.

Is this in 42.1 Current? I just tried build 0238 (Oct 18th) in a VM and still see KMix, KMixCtrl and kdeinit5 segfault at autologin (kdeinit5 not always). - JJ

It isn't in current now, but you can use OBS home:tiwai:bnc950487/pulseaudio repo.

Adding myself to this bug due to experiencing similar problems with RC1 of 42.1.
