Is this reproducible? If yes it would help a lot if you could run kdevelop through valgrind (will be slow, sorry), reproduce the crash and then attach the log. Run: $ valgrind --smc-check=all-non-file kdevelop --ps
Created attachment 90483 [details] Output of valgrind The crash is reproducible, but not when run with Valgrind. Without Valgrind the crash occurs before the following line is printed: kdevelop(3113)/default unknown: Unknown Project subclass found! With Valgrind KDevelop instead crashed only after closing its main window. I have been getting that crash for some time now but with quite useless stack trace.
I see multiple nested event loops...
