gtk_init - freezing/crashing

OK, I have two issues with gtk_init () that I can't seem to figure out...

I'm working on a GTK+ interface for Xine (  I'm
leaving as much of the existing infrastructure as is, if possible, so here
is one problem I have: Xine only gives the GUI a list of filenames for the
playlist.  Not the full argc/argv.  I therefore have nothing to pass to
gtk_init().  If I pass nothing to gtk_init(), or just the list of filenames
for the playlist (and an integer of the count of items in the list, like
argc does for argv), I get a segfault:

Program received signal SIGSEGV, Segmentation fault.
gdk_init_check (argc=0xbffff6e0, argv=0xbffff6e4) at gdk.c:429
429	gdk.c: No such file or directory.
(gdb) backtrace

#4  0x8051c96 in main ()

Now, if I do pass in some values, gtk_init() more or less freezes - it
never returns.  Interrupting gtk_init while it's in the debugger gives:

Program received signal SIGINT, Interrupt.

Xine is threaded quite a bit.  The GUI is running in the main thread, while
video/audio/etc. threads are spawned off - they do not interact with the
GUI (yet, though I plan on doing that in a thread safe way).

What could be causing this?  How can I use gtk_init() without access to
argc/argv, or do I need to make Xine pass these to the GUI code?

BTW, I'm not sure if I'm on the gtk-devel-list (I don't think I am), so
pleasae respond to my e-mail address (sean middleditch iname com).
