Here's a possibility: Looking at the code in the recorded.php page,
the file size calculations use the php gmp math functions if they're
available, and that's one of the few places where that's the case.
Maybe those are failing.

The page will use other methods for that if those functions aren't
available.  You could always try uninstalling the php5-gmp package and
restarting apache.

If that doesn't help you can always reinstall the package and restart
apache again.  In any case, that's the only thing I see going on there
that's pretty specific to that page only.
