[Comment from a bug triager]
From bug 271352 (KDE SC 4.6.0):
- What I was doing when the application crashed:
Dolphin was open with two tabs. I click on the second tab and nepumuk crashed.

From bug 264624 (KDE SC 4.6.0):
- What I was doing when the application crashed:
I was using dolphin to browse into a folder which I had previously opened
through the "+" sign (dont'w know if that's related). AFAIK, file indexing of
my folders has already been finished. Kontact may have received a new email.

From bug 264624 comment 1 (KDE SC 4.6.3):
- What I was doing when the application crashed:
browsing into my home directory with Dolphin, which was already opened
