I guess this is only true if you're using `real' Mesa.  

If you're using the `XFree86' GL libraries, then version 4.0.4 works
fine for me. 

	OS:		Debian GNU/Linux unstable (sid)
	XFree86:	4.3.0 (dfsg 1)
	GL:		xlibmesa-gl-dev 4.3.0, nvidia-glx-dev 1.0.6629

GL kept SIGSEGV on me some time ago, but that was due to an incomplete
build (my mistake).  

Yours,
