Application: kontact (4.4.10)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

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

I was using KMail to check my mail on Gmail through IMAP.  Every so often the IMAP connection hangs/times out.  This time when it hung, KMail could not access any folders at all, so I closed Kontact completely.  When I reopened Kontact, it would not start because the old kontact process (hung) was still running (these ought to be a message saying that its already running, but there isn't it just dissapears and you have to know to run a pgrep or ps aux to find the old process (I am used to kubuntu now, so I know that if a program silently fails to open then the same program is probably either running or has a zombie left over).  That's beside the point, however.

When I killed the hung process Kontact crashed and opened the bug report tool.

-- Backtrace:
Application: Kontact (kontact), signal: Aborted
