Description Geraldo Augusto Vecchiato 2010-06-08 21:38:56 UTC

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
the crash occurred after clicking the main menu. The following applications were open at the time of failure: Firefox, konsole, kwrite, pidgin, skype, amsn, kwallet, netbeans and audacious. At the time I was testing CUPS. After the failure of AMSN icon left of the notification area and go alone into a small window. The day before the notification area disappeared from the main bar, so I imagine that the problem might be related to it.

 -- Backtrace:
Application: Espaço de trabalho do Plasma (kdeinit4), signal: Bus error

please install the debug packages for 

kdelibs

and give a new backtrace

Comment 3 Christoph Feck 2010-10-14 00:27:51 UTC

(I quickly reviewed the backtrace of this crash, and it appears to be caused by KIconCache memory corruption. If this is not the case, please reopen.)

Closing all KIconCache crashes as fixed, because the KIconLoader in KDE SC 4.5 now uses KSharedDataCache to cache icons, and it is believed that the new class is less prone to random crashes or memory corruption.

If you still can reproduce a crash with version 4.5, please report it separately. If you cannot upgrade to 4.5 yet, you should be able to work around this crash by deleting the icon cache files in /var/tmp/kdecache-<user>/kpc
