           Summary: crash while before files are displaied
           Product: kompare
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kompare-devel at kde.org
        ReportedBy: nadavkav at gmail.com


Version:           unknown (using 4.2.00 (KDE 4.2.0), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.26-1-amd64

i tried to compare a local file with a remote (ftp) file using krusader and
also invoking kompare as standalone. both crashed kompare before files were in
view.

i have updated (debian experimental) several libraries a yesterday and i guess
it has to do with that since it use to work just fine (as far as i can
remember)

here is a (probably useless) crash log:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents
creation of proper backtraces, or the stack frame was seriously corrupted in
the crash.
