(*** This bug was imported into bugs.kde.org ***) Package: kdevelop Version: KDE 2.1.0 Severity: normal Installed from: Compiled From Sources Compiler: gcc 2.95.2 OS: Linux OS/Compiler notes: Not Specified 1) Create a KDE MDI application with the KDevelop wizard. 2) start it from the IDE with F9 and quit it immediately with CTRL-Q. 3) *sometimes* the application crashes. I needed to repeat the run-quit cycles 10-20 times.

Thank you for your bug report. The bug that your reported no longer applies to the latest development (CVS) version of KDE. This is most probably because the bug has been fixed the application has been substantially modified or the application no longer exists. The bug report will be closed.
Hmm... I see something that really resembles of the one reported here - but with CVS from 2002-10-22 Note the this pointer for "derefAndDelete" 0x1 - not OK. Problem from somewhere earlier...
