Bug 759123

Same here - started happening once I updated to Firefox 13 from OBS. Happens most often when opening a page with a flash video (youtube, filebox, etc). Also, the crash does not occur with 64-bit build of Firefox 13 from mozilla.org. 

Here is a stacktrace from Firefox 13 from OBS for openSUSE 12.2/x86_64:

Now as Firefox 13 will be released this crash is happening for "everyone".
Dimstar, in light of the short timeframe until 12.2 what can we do for that? Should I "conflict" in Firefox with the libproxy mozjs package or should be pull it from the release for now?

For 12.2 I think it's best to not ship the mozjs pacrunner;
as an additional safety, you can conflcit libproxt1-mozjs <= 0.4.7

this will evidently cause webkit pacrunner to be pulled in though.

I'll work on the libproxy package to drop the mozjs pacrunner for now.

*** Bug 765964 has been marked as a duplicate of this bug. ***

adding a Conflicts: libproxy1-pacrunner-mozjs <= currentversion-release 
will cause a conflict to be displayed by the packagemanagement stack.

is this easily fixable in libproxy?

we could onbsolete the libproxypack package, but this is probably not good either

We (libproxy devs) gave up trying to follow the moz API changes... And hoped that the release of a stable API would improve things.

In long term we're planning on getting theprescriber on the snide, but that will take some more time.

For 12.2 the best will be to not enable the mozjs PAC runner and obsolete it.

Just disabling does not work, but I have apatch ready in svn foot that. Well test and submit on the weekend.

I'm generally NOT convinced that this obsoletes should live in the FF package.
It's just wrong.

It has already been added to the libproxy 0.4.7 package in Factory, where it belongs (I do see need for this obsoletes in the repo itself, but NOT in Factory)

The Obsoletes was added to have a solution for 12.1 and 11.4 actually. I don't like it and it does not work for "non-patches" where it just does not allow Firefox to be updated as long as the mozjs libproxy module is installed.

I will build some conditionals around it so I can still use the same spec everywhere. (as in %suse_version < 1220)

This was addressed for 12.2.
There is not much we can do about released products besides telling users what to do manually.
