A PDF (maybe damaged while being tranferred) makes PDF interpreter to hang and print the last error line infinitely.

Hello Chris,

I've rebuilt with the patch and now it does NOT loop anymore. 

(Note that the pdf was "very corrupted" because of a wrong ftp method, text instead of binary).

Thanks a lot for your fix.

Giuseppe.
