Before calling gtk_init(), save the X error handlers with
XSetErrorHandler(NULL), XSetIOErrorHandler(NULL); after you're finished,
restore them. Thus:
void my_plugin() {
int (*old_handler) (Display *, XErrorEvent *) = XSetErrorHandler
(NULL);
int (*old_io_handler) (Display *, XErrorEvent *) = XSetIOErrorHandler
(NULL);
gtk_init (NULL, NULL);
// do stuff
XSetErrorHandler (old_handler);
XSetIOErrorHandler (old_io_handler);
}
