Bug 344580

Application: kded4 (4.12.5)
KDE Platform Version: 4.12.5
Qt Version: 4.8.6
Operating System: Linux 3.14.32-desktop-1.mga4 x86_64
Distribution: "Mageia 4"

-- Information about the crash:
- What I was doing when the application crashed:

The system was a bit more under the load and on a slow connection (in a hotel room) …other than that, nothing odd.

-- Backtrace:
Application: Ozadnji program KDE (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
gobject.pyc: gdb was not built with custom backtrace support, disabling.
