So the upstream totem-pl-parser bug (not catching max open files
exceeded) you need is:

http://bugzilla.gnome.org/show_bug.cgi?id=583473

For clarity, rhythmbox is obviously responsible for the exceeded max
open descriptors and I don't think that is directly the fault of
totem-pl-parser. The problem with totem-pl-parser is that you wind up
receiving an ambiguous mime error that has nothing to do with the actual
problem, which is that the max open fds was exceeded.

I've also filed upstream rhythmbox bug:

http://bugzilla.gnome.org/show_bug.cgi?id=583476

Maybe if I have some time on a weekend I'll try to fix the bug - it's
unfortunately increasingly difficult for a 'non-GNOME' person to keep up
with all the goings on there...perhaps you need a podcast? ;)

Jon.
