Application: kontact (4.9.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.2.0-0.bpo.3-amd64 x86_64
Distribution: Ubuntu 12.10

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

I pressed Ctrl-Q while on Kmail's tab to quit Kontact. Previously I had been editing entries in the Tasks tab.

Note: pay no attention to the kernel version reported, this is a Kubuntu Quantal LTSP container running on Debian Squeeze with the 3.2.0 kernel from squeeze-backports.

Feel free to ask me for more details, I can even provide a core dump if needed (provided it crashes again of course :) ).

Thank you,
Antonis Kanouras
