Application: kdevelop (4.1.0) KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources) Qt Version: 4.7.0 Operating System: Linux 2.6.35-25-generic i686 Distribution: Ubuntu 10.10 -- Information about the crash: - What I was doing when the application crashed: The only thing I did was selecting the "Source" tab in the upper right corner with several open source files and no project specified, and checking the functionality of the little button (don't know its name and purpose) which ise inside (on the right) of this (Source) tab. After that, the program immediately crashed. -- Backtrace: Application: KDevelop (kdevelop), signal: Aborted [Current thread is 1 (Thread 0xb78b0710 (LWP 2699))] Thread 3 (Thread 0xb74f0b70 (LWP 2700)): #0 0x00cb77f0 in __pthread_mutex_unlock_usercnt () from /lib/libpthread.so.0 #1 0x0237d701 in g_main_context_dispatch () from /lib/libglib-2.0.so.0 #2 0x02381668 in ??

I had to name the buttons according to my memory - now I want to specify the correct names: the "Source" tab was in fact the "Code" tab and the mini-button inside was the "Working set" button. The problem did not reoccur when I tried to generate the crash again in the same way.
if you ever can reproduce it with KDevelop 4.2.x, please run it through valgrind: valgrind --track-origins=yes --num-callers=25 kdevelop otherwise there is nothing to be done about it.
