Bug 327326

Application: kmail (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- Unusual behavior I noticed:
KMAIL already unusable for months, extreme slow with high cpu usage,
tried it today after a upgrade and it crashed after sending an email..
Have reported the extreme slowness before, but no reaction.

Using mutt and would love to use kmail again when the bug)s) get fixed.

Kind Regards, Peter

The crash can be reproduced every time.
