gdk_threads_enter() hangs

["Frank W. Miller" <fwmiller cornfed com>]

Greetings,

I'm having some strange behaviour.  I am writing a threaded Gnome app 
and it seems to be hanging when I call gdk_threads_enter().  Here's the 
code snippet where it hangs up:

>                                                                                
>  
> printf("gdk_threads_enter()\n");
>                 gdk_threads_enter();
> printf("gdk_threads_enter() returned\n");
>                                                                                
>  


The output is (as you might guess):

> gdk_threads_enter()


The second printf is never executed.  I've been over all my various 
gdk_threads_enter()/gdk_threads_leave() pairs to make sure I'm not 
locking GDK and then not unlocking it.  It seems to me to be fine.  All 
the protected areas are very short, i.e. 1 or 2 lines of code, and the 
protected code is all just calls to gtk stuff.  I'm not doing any I/O 
inside of a protected area.  Any thoughts on this?


Thanks in advance,
FM
