I'd suggest switching to gtk2. It is much better than gtk1.

What do you need the threads for? 

If you want to do some background processing and have your GUI update
at the same time, it is almost always better to g_idle_add() a
function to do the processing and then in that function do

        while (gtk_event_pending())
                gtk_main_iteration (FALSE);

to allow events to be processed.

Alternatively, if you really need to update the GUI from a thread, do
g_idle_add (function_that_does_the_updating, ...). In this case,
"function_that_does_the_updating" will be called from the thread that
runs the main loop, so it can safely call gtk functions.
