Bug 331779

Application: kded4 (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.13.5-101.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed: back from standby. I suspect that this happen when I have browser with some flash content. Ex. watching videos from internet.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
