           Summary: Crash on startup
           Product: kmail
           Version: 1.13.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: ghost at cs.msu.su


Application: kmail (1.13.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic-pae i686
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
KMail started to crash every time I start it, see enclosed backtrace. Editing
kmailrc so that all occurences of MainFolderViewItemIsExpanded=true are changed
to 'false' appears to fix this problem.

The crash can be reproduced every time.

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