This error means something along the lines of:

 - You called GTK+ from a thread without taking the necessary precaution
   (read the FAQ and make sure to call gdk_threads_init() which is
   needed since GTK+-2.0)
 - You called out GTK+ out of a signal handler
 - You forked and continued use GTK+ in the forked process

It's basically saying "Xlib is confused"
