pdftotext crashed with SIGSEGV in Dict::lookup()

this bug has been reported here:

https://bugs.edge.launchpad.net/ubuntu/+source/poppler/+bug/213852

"It crashed out overnight, I believe it was linked to the file indexing that the tracker program was doing at the time. As the only other thing that was still running was Transmission, since I was downloading a couple of torrent files."

He ran pdftotext on something called /home/username/Downloads/torrentfile.ext which does not seem to be a pdf, crashing of course is not ok, but without the exact /home/username/Downloads/torrentfile.ext that made the app crash there's little we can do.

One year after me asking the file noone has answered, closing the crash. Please reopen if you have the file that makes pdftotext crash.
