Right, my bad, I've got confused with the actual Tesla card.

I gave it a spin today and the trace I gathered doesn't crash when replaying as
you suggested. The bottom of the trace contains an incomplete glFlush() call
followed by a glDrawArrays() which is also incomplete. I'll try grabbing more
traces in the hope of finding one that reproduces the crash.

Alternatively if you have the appropriate hardware to reproduce I can walk you
through how to build this stuff and reproduce yourself (it's a procedure that
might take a few hours though, the full Firefox OS emulator build is *large*).
