[Josh Matthews [:jdm]]

Crashing line is:

>99  aAdapterDescription.AssignASCII(mozilla::gl::GetVendor());

and the crash address of 0x0 implies to me that we're calling strlen on a null pointer. Graphics folk, is this something we would expect to be happening?

This doesn't seem to touch the section of code that I've been working on recently. I can look into it but I need to get my Android dev environment set up first.
