Thanks for looking into the issue. While your at it: I spotted another 
potential bug, but I didn't construct a minimal example so far. But 
maybe the bug is obvious without an example:

In the "breakLinesCJK" method in paragraph.py the paragraph height 
(self.height) is set too late in certain circumstances. I moved 
self.height = 0 above the two return statements - this fixes the 
problem. See the diff below. If a minimal example is required I'll try 
to supply one.

Regards,
Volker
