[GtkGLExt] pixmap.c example crashes under fedora 8

Hi all,

I have an application with a problem using a gdk drawable pixmap. I therefore tried compiling the pixmap.c example and it does the same thing.

The X error suggests running with --sync and breaking on gdk_x_error to get a backtrace. The relevant part of the backtrace is

#0  gdk_x_error (display=0x9fdb020, error=0xbfb9a398) at gdkmain-x11.c:614

Is this a known issue, and is there a fix or work around.
