This looks like either a double deletion or dangling pointer. Can you run valgrind on the process and make it crash? [New Thread 1024 (LWP 5248)]

seems to be exactly the same - and on my system (kde3.2cvs; kdevelop-cvs both last week ) i can reproduce it 100%
As soon as i use dotNET Style, kdevelop produces this crash at exit.
Switching to another style, kdevelop does not crash at exit.
i came to the idea of style-switching, because of this valgrind-output:

( but i guess, this is another issue, if it is one )
the crash itself is reported by valgrind:

but i don't get any more information out of this.
I'm using keramik KDE 3.1.92 kdelibs/kdeui contains ktabwidget.cpp .h and kdevelop/lib/widgets contain ktabwidget.cpp .h but these are different implementsation of the same class, which causes the crash in the destructor. Remove the kdevelop/lib/widgets version and recompile from scratch. If you look at kdevelop-devel mailing list you'll find a patch that fixes this for >=kde 3.1.90 but it doesn't work for kde < 3.1.90 release :( I think there are other issues with headers and the compat/widgets library as well. This really needs a fix but I have no time. Could someone please please please look into this problem. I mailed a second patch for half of the problems I found that should work for kde > 3.1.90 but nobody has tested on those versione so I cannot commit that. (The second patch doesn't fix this problem though) See thread "class libs/widget/KTabBar conflicts with class kdelibs/kdeui/KTabBar" 12/Oct/03 *** This bug has been marked as a duplicate of 61604 *** Using CVS from yesterday ....
