           Summary: Infinite loop in "Save diff" when compared files are
                    on different drive letters
           Product: kompare
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kompare-devel at kde.org
        ReportedBy: krissn at op.pl


Version:            (using KDE 4.4.3)
Compiler:          MSVC 9.0 
OS:                MS Windows
Installed from:    Compiled From Sources

On MS Windows, when comparing two files that are residing on different drive
letters, Kompare falls into an infinite loop after selecting the "Save diff"
option.

The reason for this problem is that Kompare tries to find a common root path
for both files. On Unix there is always one common root for all files, while on
MS Windows this is not the case. Kompare will try to walk up the path, but once
it hits the root directory of a drive, it won't detect, that it can't go any
further and will keep trying.
