Can you send in the graphics section of about:support?

I'm also seeing this OOM (bug 1028491 comment 14). It puzzles me that this is so reproducible even on a fresh launch when I have the entire address space available. Can we trust the OOM size annotation? 16k makes no sense.

Josh can you try Bing Maps again on the latest Nightly or Aurora? For me it seems to have been fixed by bug 1046528.

Yep. I can confirm it's fixed.
