Bug 273736

Application: kontact (4.4.10)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:  I had switched to use a different application because Kontact had become unresponsive.

- Unusual behavior I noticed:  I was switching between Kontact (Kmail) windows when the application became unresponsive (window would raise, but wasn't drawn).  All other apps were fine, so I move on to something else.  Several minutes later it finally crashed.

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