More generally, if you want to serialize objects that don't have plain content, for instances objects containing resources, you need to implement __sleep and __serialize to provide (un)serialize with a means to store what information you want to serialize, because it has no way to get to it on its own. 

See http://fr2.php.net/manual/fr/language.oop5.magic.php#language.oop5.magic.sleep

This is basically what you work around by converting to XML text: you removed the hidden info, just like a _sleep implementation would do.

Your google approach was correct: http://drupal.org/node/529866 has a good rundown on this.

I've also had major serialization issues with simplexml. In that case you have to store XML into the cache after converting to xml using simplexml's methodology - you can't just dump a tree into the drupal cache.

I asked about this at #drupal-support, and am waiting for an answer, but when I Googled it (+unserialize +"Error at offset" +"bootstrap.inc") I received 220,000 postings, so maybe this is a big issue I missed?  Unserialize error at offset x of y bytes in boostrap.inc?
