Bug 320136

Application: kded4 ($Id$)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-43-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- Unusual behavior I noticed:
Iphone keeps disconnecting and reconnecting to usb automatically, entire desktop crashes then reloads.  Applications that were running stay running though (FF, T-Bird, pidgin, etc)

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
