            Bug ID: 295676
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: kmail crash on compose new email
    Classification: Unclassified
                OS: Linux
          Reporter: malte.gerth at googlemail.com
          Hardware: Ubuntu Packages
            Status: NEW
         Component: general
           Product: kmail2

Application: kmail (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
i started kmail instead of kontact, as kontact behaves extremly slow after
upgrade to 4.8.1 with kubuntu backports 11.10
reading and moving mails worked, but when i clicked on New Mail button the
application crashed

- Unusual behavior I noticed:
mysqld and virtuose-t process takes very much cpu. KDE at all seems very
unstable after the upgrade to 4.8.1

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
