Bug 341303

Application: kded4 (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.17.2-1-desktop i686
Distribution: "openSUSE 20141112 (Harlequin) (i586)"

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

After starting vncserver 5.2.1 on OpenSuse 13.2/tumbleweed, using ~/.vnc/xstartup:
---
#!/bin/sh
dbus-launch /usr/bin/startkde
---
this crash occured while connecting from a windows 7 machine running realvnc viewer 5.2.1.

The crash can be reproduced every time.

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