           Summary: Crash when closing a project
           Product: kdevelop
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: chris at hypocrite.org


Version:           3.0a5 latest CVS (using KDE KDE 3.1.2)
Installed from:    Gentoo Packages
OS:          Linux

I start up KDevelop (Gideon 3.0a5, latest cvs).  It automatically opens my previous project.  I go to the project menu and select Close.  KDevelop crashes.  The same thing happens when I try to open a different project, presumably because it has to first close the current project.

This is happening with 100% reproducability.  I updated from cvs today, normally do so every couple of days.  I had never seen this before.

Here is my backtrace from gdb:

Here is what KCrash grabs, probably not useful:

I have tried recompiling KDevelop (make clean, reconfigure, remake) both in release mode and in debug mode.  The same problem occurs both times.
