           Summary: crash after adding a folder to favorite folder list
           Product: kmail2
           Version: 2.0.89
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: m.wege at web.de


Application: kmail (2.0.89)
KDE Platform Version: 4.5.90 (4.6 RC1)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-11-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: I added a folder to the
favorite folder list, then the crash happened. The funny thing: I had done this
before. This was number 6 or 7, before that, there was no crash. Kmail crashed
repeatedly on restart until I removed the configs about favourite folders. The
last folder added did not contain any unusual character. When trying to
reproduce the bug, just adding the folders did not do any crash. But starting
to rename the folders (essentially removing the mailbox name) Kmail started to
behave odd: First one of the folders appeared double, then 2 of the folders had
the option to rename it greyed out. Deleting the double folder -> crash again

- Unusual behavior I noticed:
