Re: [gtk-vnc-devel] PATCH: Fix crash in OpenGL scaling code

[Rob Stoddard <rstoddard telanetix com>]

I didn't find it in a bug report, I found it on the mailing list.  
Apparently there was little done about this issue, setting the 
environment variable was the only fix that was discussed, if you call it 
a fix.

and sorry bout the typo, the env variable is:

GDK_GL_NO_STANDARD_COLORMAP
