Thanks. But when I read the docs about gdk_threads_enter/leave funcs I 
don't remember anything saying that gtk_main() also needs those...

And it worked on my Mandrake 9.1 too.

Noooooo! :(
How can I write a GTK+ app for networking? The user clicks on a 
"Connect" button, and the resolve/connect operation is made in a 
separated thread. The docs says:

--
"Callbacks require a bit of attention. Callbacks from GTK+ signals are 
made within the GTK+ lock. However callbacks from GLib (timeouts, IO 
callbacks, and idle functions) are made outside of the GTK+ lock. So, 
within a signal handler you do not need to call gdk_threads_enter(), but 
within the other types of callbacks, you do."
--

So this means that even with a gtk_idle workaround I won't be able to 
update the GUI?
