           Summary: Kdevelop crash when double clicking on a source file
           Product: kdevelop
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: davide.rondini@gmail.com

Application that crashed: kdevelop
Version of the application: 3.9.95 (using KDevPlatform 0.9.95)
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.27.30-170.2.82.fc10.x86_64 x86_64
Distribution: "Fedora release 10 (Cambridge)"

What I was doing when the application crashed:
Kdevelop crashed when double clicked on a source file in my project tree. When
re-started Kdevelop, re-opened the project, and double-clicked again on the
same file, and the crash re-happened. It looks like the code parser don't like
something in my code.
