Comment (by bobbingwide):

 Replying to azaozz. I would have hoped that most functions would produce
 an error message if they were able to detect a problem with the parameters
 or API usage. Before I update the wiki I'd like to find out what the
 WordPress strategy is towards parameter validation and error handling.

 To all readers: the main problem I had was that I didn't see any messages
 when the error occurred. Not even in log files. I have now tracked this
 down to some over zealous code in the wpStoreCart plugin. When I
 deactivate that plugin, then I do get to see:
 Fatal error: Uncaught exception 'Exception' with message 'Serialization of
 'SimpleXMLElement' is not allowed'

 So the lesson learned is - always try to reduce problems to the simplest
 case,remove any excess baggage. PS. I had a different problem just a
 couple of days ago... and wrote about it at
