Bug 321663

Application: kded4 (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.8.0-26-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Had wine running, but was idle
Also jabref, okular and kmail, and amarok

This just poped up while i was doing nothing but looking into okular.
Don't know if this is meaningful in any way. But there where no duplicate bug reports.

Greetings.

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