           Summary: PartManager does not inform its parts that it is going
                    to be destroyed
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR

Version:           gideon HEAD from approximately 13/09/2002 (using KDE KDE 3.0.7)
Installed from:    Compiled From Sources
OS:          Linux

I came accross a bug which causes gideon to crash on leaving. 
The bug is located in the PartManager of kdelib-3.0.7. The PartManager does not inform its parts if it is about to be destroyed. Therefore, a part tries to access its PartManager, even if it is gone. The following patch takes care of this bug:

*** ../../temp/kdelibs-3.0.7/kparts/partmanager.cpp	Mon Aug  5 17:39:45 2002

    // core dumps ... setActivePart( 0L );
    qApp->removeEventFilter( this );

+   // Inform all parts that their manager is gone.
+   QPtrListIterator<Part> itpart ( d->m_parts );

+       itpart.current()->setManager(0);

    delete d;
