A source code comment tells "indicates a PDFBox bug".

Indeed it does, thought in this case it was actually a problem with the font, some of the charstrings contain "0 0 [15]" but 15 is not a valid charstring command in Type 1 and it's reserved in Type 2.

I've fixed this by ignoring and warning truely unknown commands in [r1608985|http://svn.apache.org/r1608985].
