You could check if you have "wild" Client State somewhere ("wild" like 
in "wild pointers"). It is easy to forget to call glDisableClientState 
for some of GL_..._ARRAY capability when it no longer needed. And in 
such case error might manifest it self in an unusual way, just like in 
case of generic dangling pointers.
