Pathfinder Advanced Players Guide OOC Data Set seems to break character sheet printing

Reported by Samuel Robinson:
We are getting an error about 80% through rendering that XML document
structures must start and end within the same entity. I can think of a
number of things that could cause such a message, but have not troubleshot
this yet. I recommend restraint until this is understood. It seems to happen
with all character sheets, but not spell books.
