           Summary: Crashed when diff'ing two directories
           Product: kompare
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kompare-devel at kde.org
        ReportedBy: seanthenewt at yahoo.com


Application that crashed: kompare
Version of the application: 4.0.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I tried diff'ing two directories by running the command kompare dir1 dir2&.
That resulted in a blank diff, so I tried selecting the two directories
manually using the GUI. The crash occured after I had selected the two
directories and clicked on the button to perform the diff.

 -- Backtrace:
Application: Kompare (kompare), signal: Segmentation fault
The current source language is "auto; currently c".
