util: avoid crash due to race in glib event loop code
we need to do this in the other event loop as crash in that one was also
reported:

This one isn't desirable as it'll cause a memory leak. This method is the
very thread that was running the event loop, so there's no possibility
of a race condition. Also the loop has stopped running at this point,
so the idle source will never run. Just drop this hunk
Regards,
Daniel
