g_thread_init() and gtk_init() segmentation faults

[Richard Baverstock <baver thebeever com>]

I'm trying to write a (GTK+2) program with multiple threads using g_thread_init(), but I have yet to figure 
out how without receiving segmentation faults. The following is the snippet of code that invokes 
g_thread_init() and calls gtk_init().

int
main (int argc, char *argv[])
{
  GtkWidget *menu_bar;
  GtkWidget *toolbar;
  GtkWidget *hbox1;
  
   g_thread_init(NULL);
   
   gtk_init(&argc, &argv);

  bb_read_options_file ();
  if (options.start_project)
    options.project = options.start_project;

...


and it goes on.

Yes, it's compiled with -lgthread-2.0 and not -lgthread. Well, I actually use pkg-config --libs gthread-2.0, 
which has that.
Using gcc 3.2.2 with posix thread support compiled in.


Currently, with this, I get a segmentation fault at gtk_init(&argc, &argv);. This is the output from gdb:

I am at a total loss as to what I am doing wrong. I've tried IRC channels, forums, mailing lists archives 
etc. It's bound to be something ironic. Anyways, if anyone can help me figure this out, it will be much 
appreciated.
