I had encountered this a while back: Loading http://meta.wikimedia.org/wiki/User:Mike.lifeguard/Screencasts gives a white page. Brion did some investigation back in the day and said (IIRC) that viewing the page pulls file metadata, which can cause an out-of-memory condition when the files are very large. I guess the solution means loading metadata without pulling the whole file into memory, or not loading metadata (if that's possible).
This bad boy is bug 19476... rumor there is that some large image files may also have this problem fetching EXIF data but the Ogg one seems the worst. *** This bug has been marked as a duplicate of bug 19476 ***
