Feed failing to parse in planet 2.0

[Matt Smith]

I'm using the 2.0 release tarball of planet and it works perfectly except
on one certain feed. The feed in question is
http://feeds.feedburner.com/ICanHasCheezburger and it produces this error
when planet tries to parse it:

I've run this feed through the feed validator and whilst it doesn't
validate it only has one problem apparently which you can see at
http://feedvalidator.org/check.cgi?url=http%3A%2F%2Ffeeds.feedburner.com%2FICanHasCheezburger
which is:

line 14, column 206: feedburner:emailServiceId must be a positive integer:
k5j89m14789ssbpekrrprd3hh8
...
mailServiceId>k5j89m14789ssbpekrrprd3hh8</feedburner:emailServiceId><fee
...

I've tried removing this particular attribute on a local copy and the feed
then validates perfectly but planet still gives the same error.

Any ideas how I can make planet work with this feed?

Regards, Matt.
