Comment 2 Christoph Feck 2010-10-14 00:27:02 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
