I can repro this issue on my Linux machine.

http://hg.mozilla.org/mozilla-central/file/c482c28b35b6/content/media/MediaCache.cpp#l2413
I hit this assertion and found out |startOffset| equals |endOffset|, therefore it could never exit the while loop and hanged forever.

The website no longer exists and I don't have a long mp4 file to test with. With a large ogv file it works fine.

Maybe we should just close this issue?
