Re: GConf problems

[Gustavo Joćo Alves Marques Carneiro <ee96090 fe up pt>]

   I did make a small test program. See the attachment. 

   I think the problem is related to some threads -- maybe some
deadlock. You can see in the backtrace below, that the program halts in a
pthread_mutex_lock.  Also, the deadlock only happens sometimes.  

   Could it be that I made a mistake? Should I call gdk_threads_enter
before unref'ing  the GConfClient object?
