Description chris 2009-05-18 17:15:01 UTC

Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    SuSE RPMs

I get 6 plasmoids running on the screensaver.
Each times I leave it, a SIGSEV error appears.

It gives this :
Cette pile des appels apparaît être inutilisable.
C'est probablement dû au fait que votre paquetage a été construit d'une manière qui empêche de créer des piles d'appels corrects, ou que le cadre de pile a été sérieusement corrompu dans l'incident.

i should point out that the french message is most useless to the majority of those who will look at this report. ;)

Comment 2 Dario Andres 2009-05-19 00:42:24 UTC

As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here?
You need to install the "kdelibs5-debuginfo", "libqt4-debuginfo" packages (may be "kdebase4-*-debuginfo" package too)
 Thanks

Comment 3 chris 2009-05-20 17:50:33 UTC

Now, I installed some debug package, the backtrack gives that :
