Comment (by markjaquith):

 I did a svn switch to /branches/2.1/ before reporting.

 In order for the cache to be enabled, your wp-contents directory needs to
 be writable (it should create a /cache/ directory).

 In any case, I discovered the issue.  {{{get_category()}}} tries to store
 an array of object references into the cache.  The cache doesn't like
 this, and stores a blank string instead.  So you get a blank string on the
 way out.

 Looking around the web, it seems like good old serialize/unserialize is
 the sure way to make sure you don't have any references.  Patch adds that
 to the appropriate cache functions.
