Removes an error trap pushed with gdk.global.errorTrapPush. May block until an error has been definitively received or not received from the X server. gdk.global.errorTrapPopIgnored is preferred if you don’t need to know whether an error occurred, because it never has to block. If you don't need the return value of gdk.global.errorTrapPop, use gdk.global.errorTrapPopIgnored.
Prior to GDK 3.0, this function would not automatically sync for you, so you had to gdk.global.flush if your last call to Xlib was not a blocking round trip.
