           Summary: Sig11 when interrupting "Swap Source and Destination"
           Product: kompare
           Version: 4.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kompare-devel at kde.org
        ReportedBy: xanthraxoid at yahoo.co.uk


Application: kompare (4.0.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic-pae i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I opened two directories, applied some changes and swapped source with
destination to apply some changes the other way.

While it was still processing (took a while because the files were mounted on
sshfs) I absent mindedly clicked the button to apply another change.

Sig11!

The crash can be reproduced every time.

 -- Backtrace:
Application: Kompare (kompare), signal: Segmentation fault
