[Comment from a bug triager]
From bug 272402 (KDE SC 4.6.2):
- What I was doing when the application crashed:
I was searching for a mail with kmail... then i decided to open (in the same
time!) a folder on the desktop... also this crash appeared!

From bug 275384 (another situation):
- What I was doing when the application crashed:
Hi, I just closed the systemsettings dialog (I set-up KDM login dialogues) and
nepomuk crashed.
