Can you reproduce this issue? I've never seen a backtrace such as this one, it hints at some internal issue in QProcess or similar.

If you are able to reproduce it, please run kdevelop through valgrind and see whether you can find anything:

valgrind --track-origins=yes --smc-check=all-non-file kdevelop -s ...
