Um... Well, the idea behind including gtkglext in the openvrml 
distribution and using its libraries as convenience libraries is that 
users shouldn't *have* to have gtkglext installed.

You will need to use gdb to get a backtrace. Easiest way is probably to 
attach gdb to the running process before you load warbird.wrl:

    $ gdb --pid=<openvrml-xembed-pid>
    (gdb) c

    [now go load warbird.wrl in openvrml-player and make it crash]

    (gdb) bt
