Application: kontact (4.10 rc3)
KDE Platform Version: 4.9.98
Qt Version: 4.8.2
Operating System: Linux 3.2.0-36-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

I start kcontact with Mails hosted on a remote IMAP server. 
The reading of the mails work. Now I tried to modify the sieve scripts on the server.
With the last KDE version kde 4.10rc2 this was possible.
Now after upgrading to kde 4.10rc3 kcontact will crash as soon a I hit the button

Manage Sieve scripts

The crash can be reproduced every time.

-- Backtrace:
