Application: kded4 ($Id$)
KDE Platform Version: 4.9.97
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic i686
Distribution: Ubuntu 12.10

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

I had resumed my laptop from suspend to RAM and saw the DrKonqui crash window.

This bug is a duplicate of many other bugs, but I'm reporting it nevertheless because:
 - it concerns the most recent KDE version (4.9.97 aka 4.10RC2)
 - I had restarted kded4 in a terminal (after killing it to work around a memory leak) and therefore I have a clean debug output

Here is the debug output:
