Hm, strangely enough, this error assert is commented out for Linux even 
though there is a comment saying that it should be enabled for that 
platform, too. :)

I'm tempted to turn it on and see what happens.

GL's error reporting mechanism is a bit unusual in that function never 
directly return error codes but instead you have to check a 
(context-)global variable every now and then. So to pinpoint the exact 
call which is responsible for the "invalid" you need put a lot of 
glError()-calls into the code and find the spot where it changes.
