I've got 0.11 installed on RH9.  My wife has excellent bug karma
and got the mythfrontend application to deadlock by just hitting
the menu button out of live tv.  I attached to the hung process
and here is the stack trace.  I don't know what else to provide
to you, but I can keep the gdb running for a while to help you
