........

looks like there's a dictionary with an empty key. Can you just wrap the call at 
line 621 thusly.

try:
     L = [(format(PDFName(k),document)+" "+format(dict[k],document)) for k in keys]
except:
     print ['%r=%r' %(k,v) for k,v in dict.items()]
     raise

that may give some clue as to what kind of dictionary it is?
