Application: kmail (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I has kmail running on one computer, with its main window hidden. At some point I connected from another computer and invoked kmail from the command line. 
- Unusual behavior I noticed:
On start I got a long list of nepomuk error popups which I unfortunately ignored. I was able to read new messages but none of the messages I read were marked read. I also couldn't delete any messages.
Shortly afterwards I tried to reopen kmail directly on the computer where it ran. I got messages that kmail is unable to connect to its mail boxes.

When I tried to shut down the computer, this crash happened.

-- Backtrace:
