vlad: please say you have debugging symbols somewhere where they can be reached.

tyler: sadly if vlad and co have no provided symbols for canvas3d, then the general instructions won't result in anything useful (the stack indicates that the reporter actually has symbols for the mozilla bits, although oddly no symbols for msvcr80.dll for which .symfix+ would have solved)

Sorry, I didn't get a chance to respond here yet -- this is known, I have a fix in hand, just working through some problems for builds.

assuming you've actually updated, please file a new bug. we don't need one bug per crashing library otherwise, we'd have about 50 bugs total in our system and we'd never manage to keep them closed.
