           Summary: Crash when using the GDB command-line
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: dima@gmail.com


Application: kdevelop (3.10.2 (using KDevPlatform 0.10.2))
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I'm not 100% sure, but I think I was about to type a GDB command when KDevelop
crashed. I was already experiencing weird behavior with the GDB command line:
bug 235501.


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