           Summary: reproducible crash with closing file in "Qt based text
                    editor"
           Product: kdevelop
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: tuimonen at cc.hut.fi


Version:           3.0.0b (using KDE KDE 3.1.4)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc version 3.3.2 (Debian) 
OS:          Linux

Start kdevelop
Set Editor to "Qt Designer based text editor" (Settings->Configure KDevelop->editor)
Open some file
Right click on editor window
(from popup)->Application->Close
CRASH

I ran also under gdb, and after SEGFAULT, I did "thread apply all bt" (like when debugging Ardour..), but nothing fancy came up, just few libc routines.

Here is the shell output (starting from the right click action to the crash)
