Bug 308052

Application: kded4 ($Id$)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
I reinstalled Ubuntu and now every time I start my computer the KDE crash handler appears. This doesn't appear to be related to any previous bugs because the bugs that appeared in the suggested list in the KDE crash handler app seemed to be totally random.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
