           Summary: KDevelop crashes when trying to open a file
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: janitor048 at googlemail.com


Application that crashed: kdevelop.bin
Version of the application: 3.9.99 (using KDevPlatform 0.9.99)
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
KDevelop (3.9.99 from svn) crashes when I try to open any file (.cpp and .h
files for what it is worth) either via the file->open dialog or directly by
double-clicking in the project overview. This bug is reproducable.

Cheers,
Oliver
