Reproducible: Couldn't Reproduce Steps to Reproduce: Occured at least twice with the almost same scenario, but irreproducibe when it needed.
Created attachment 69295 [details] crashdump Cannot report this bug via standard KDevelop mechanism, it cannot login to bugzilla and shows me a HTML page with my logged-in account.
the backtrace shows that you closed the app and it then crashed on exit, so this is completely unrelated to working sets. if you can reproduce this, please do so. a valgrind log is always very useful as well: valgrind --track-origins=yes --num-callers=25 kdevelop *** This bug has been marked as a duplicate of bug 261111 ***
