Description Antonis Kanouras 2012-11-08 14:06:21 UTC 
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

New crash information added by DrKonqi

kontact (4.8.5) on KDE Platform 4.8.5 (4.8.5) "release 2" using Qt 4.8.4

- What I was doing when the application crashed:

Read e-mails in Kmail/Kontact mostly on IMAP accounts, delete some of them, then quit immediately.
(close the Kontact window with mouse clic on the X button decoration)

May be some IMAP syncs were still running ?
