Application: kded4 ($Id$)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.2
Operating System: Linux 3.5.2-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I logged in to KDE IM Contacts with an old account I hadn't used in a while and received a bunch of scammy friend requests. I right clicked on the new icon that appeared in the panel and started denying each of them. After ~3 that icon goes away and this crash report dialogue comes up. KDE IM Contacts stays running.

The crash can be reproduced every time.

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