Sentry Crash Report:

Description Birgit Nietsch 2011-12-16 08:35:57 UTC 
Application: kmailcvt (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic-pae i686
Distribution: Ubuntu 11.10

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

1. started kmailcvt
2. selected Pegasus Import
3. selected local folder as the import target
4. selected OK.

kmailcvt imported my mails and crashed afterwards. 
Not sure if everything has been imported.
This happens every time I'm importing mails from my postbox on our mercury mailserver, which is: daily.

The crash can be reproduced every time.

-- Backtrace:
Application: KMailCVT (kmailcvt), signal: Segmentation fault

I want to debug it.
But it's necessary to have email from pegassus.
Where I can found a pegassus apps ? or a small tarball of pegasus mail ?

Comment 4 Laurent Montel 2011-12-16 13:38:02 UTC 
So it was easy.
Backtrace gave me info how to fix it.
It's fixed in 4.8 or if you compile from source I backported to 4.7.x

Thanks for report
(but if you can told me where I can find pegasus...)
I will try to improve import from other mail apps.
Comment 5 Birgit Nietsch 2011-12-17 10:41:48 UTC 
Hi Laurent,
thanks for fixing, I will try it out on monday.

About your questions on Pegasus:
You can get the Pegasus Mail Client and the Mercury Mail Server 
from http://www.pmail.com/ if you want to generate test data, but 
unfortunately both will only run on MS Windows. You can try it on 
wine and at least Pegasus will run, but the last time I  tried 
that myself, it totally lacked network connectivity.

Best wishes and seasonal greetings
Birgit
