I actually suspect that Christian ran either into this problem or that he doesn't compile with -threaded. Hopefully it's one of those two options and not another concurrency bug in Gtk2Hs. So the story with the threads is as follows: You can use just a single thread. This is done when you compile without -threaded. You need to do the 'addIdle 50 yield' trick. You can use the -threaded option to ghc or you use ghci. Now there exists one lock for the whole of Gtk+. This lock must be acquired before gtk_init is called. (This is what I fixed before the release: without it, it worked on Unix but not on Windows.) The lock remains acquired by the OS thread that calls Gtk+. In particular, it remains acquire as long as signals are pending and dispatched. The only time this look is released is when Gtk+ enters its main loop. It may then block on input or run an idle handler. During this time, it is possible for a different OS thread (or any odd Haskell thread that may or may not run in a different OS thread) to acquire the lock, modify some widget state and release the lock. However, most widget methods call also to the OS and accessing the Win32 API from more than one OS thread is not possible due to Win32 using some thread-local state. Thus, using this method for concurrent updates is not recommended. Enter postGUIAsync. This method will add an idle handler to the Gtk+ main loop (this is done by glib in a thread safe way) which executes an action from the idle handler. This idle handler will be called from the main loop and thus be in the Gtk+ OS thread. The action can therefore safely access all widget methods. Since the action is performed in the Gtk+ OS thread, no expensive computation should be done, merely the widgets should be updated. I hope this helps to clarify the thread situation in Gtk+.
