           Summary: Kompare crashed when I selected next directory

          Priority: NOR
         Component: general
        AssignedTo: kompare-devel at kde.org
        ReportedBy: carterqw at googlemail.com

-- Information about the crash:
I was comparing two directories, using GUI buttons to navigate. Then decided to
go straight to the particular subdirectory, so I clicked on that subdirectory
in the tree and Kompare crashed.
