Bug 241404

Application: kontact (4.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic-pae i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Kmail crashes clicking on cancel while downloading the text of the message after selecting reply to all.
It seems  that download hags for some unknown reason and clicking on cancels triggers the crash.
I do not know if the same apply to a simple reply (not to all).

The crash can be reproduced every time.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
