[opensuse] gtk 64-bit problem

I'm having a problem running some gtk code. I encountered a problem
installing the Perl bindings to gtk but it seems to be related to the
underlying Suse gtk package. I built and ran the following C program:
/* gcc `pkg-config --libs --cflags gtk+-2.0` dialog.c -o dialog */
#include <gtk/gtk.h>
int
main (int argc, char **argv)
{
GtkWidget *dialog;
gtk_init (&argc, &argv);
dialog = gtk_file_chooser_dialog_new ("Test",
NULL,
GTK_FILE_CHOOSER_ACTION_OPEN,
GTK_STOCK_CANCEL,
GTK_RESPONSE_CANCEL,
GTK_STOCK_OPEN,
GTK_RESPONSE_ACCEPT,
NULL);
gtk_widget_destroy (dialog);
return 0;
}
It runs to completion when run by a normal user, but hangs when run as
root. Furthermore, gdb complains about internal errors.
I'm not familiar with gdb but there's a log below. It hung when run, I
typed CTRL-C then when I did 'bt' it said there was an internal error in
gdb.
I tried again (see second log) and single-stepped main but it hung
immediately. The third log is the result of single-stepping as a normal
user.
I'm on an AMD 64 system with Suse 10.2. Has anybody seen anything like this? Can
anybody reproduce it?
Cheers, Dave
