Bug 318788

Application: kded4 ($Id$)
KDE Platform Version: 4.10.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-40-generic-pae i686
Distribution: Ubuntu 12.04.2 LTS

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

I was in the Kontact application, and I had the Zanshin component selected ("Todo Lists"). 

I use the separate app menu on top of the screen. My system was sluggish since it was under load,  and when I selected "Settings → Configure Kontact" in the menu bar it took a while for the configuration window to show up. Before it showed up, I clicked again on "Settings" and moved the mouse over the menu items. That's when kded crashed.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
