Description Heiko Schmidt 2006-11-29 22:46:10 UTC 
while configuring the tv-card and using the expert-modus the application close itself by clicking on the "Load Kernel Modules" button
Comment 1 Matej Horvath 2006-11-30 10:25:12 UTC 
Please attach your yast log files.

Thank you.

Comment 3 Ladislav Slezák 2006-12-07 13:23:51 UTC 
I cannot reproduce it in the final version (RC5), yast displays list of the kernel modules correctly.

Please, run 'Y2DEBUG=1 yast2 tv' command and attach yast logs again.
Comment 4 Heiko Schmidt 2006-12-07 23:21:12 UTC 
Done, see attachment

Output was:
# Y2DEBUG=1 yast2 tv
Segmentation fault at Tv.ycp:546

Comment 8 Paul Watts 2007-01-15 16:24:13 UTC 
Note same error occurs during install when TV cards are autodetected, causing yast in install mode to crash out.  Error is exactly the same as Heiko above.

Upon restart yast steps back to the 'check for updates' stage.  Strange!
Comment 9 Paul Watts 2007-01-16 11:33:24 UTC 
Further to previous comment - observing this behaviour in openSuSE 10.2 final release.  Not apparant in 10.1 released version either.
Comment 10 Ladislav Slezák 2007-01-16 13:55:55 UTC 
It seems that 80211.ko kernel module makes problems in yast.

Yast crashes in regexp call:

  foreach(string regexp, regexps, {
    if (regexpmatch(m, regexp))

because m is 80211 (integer, although declared as string!) -- it seems that either YCP interpreter or modinfo agent is broken.
Comment 12 Martin Vidner 2007-01-19 16:29:57 UTC 
Indeed, the modinfo agent has the classic bug of producing numbers out of strings that look like numbers.
Comment 13 Martin Vidner 2007-01-22 10:01:40 UTC 
Fixed for 10.3 in yast2-core-2.15.3 and for SLE10 SP1 in yast2-core-2.13.35.

The fix is this:
