           Summary: crash when closing open file
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at barney.cs.uni-potsdam.de
        ReportedBy: jeremyhu at uclink4.berkeley.edu


Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.2 
OS:          Linux

Quite frequently (about 2% of the time I'd guess), closing an open file causes kdevelop to crash.  I am using a recent dvs snaphot of kde 3.1 and kdevelop 2.1.4, but this has occured with older shapshots and 2.1.3 as well.  I currently have qt 3.1 installed as well.  I use the tab-page mode interface.

here's the bt:
