Error when trying to OCR JPEG or PNG

[shaunc869]

When I try to run:

sudo ocrmypdf --verbose 3 eiffel.jpg eiffel.pdf

I get:

Original exception:
Exception #1
  'builtins.TypeError(Can't convert 'list' object to str implicitly)' raised in ...
   Task = def ocrmypdf.main.split_pages(...):
   Job  = [[] -> .../com.github.ocrmypdf.45n_qza7/*.page.pdf, <ocrmypdf.main.WrappedLogger>, [], <_thread.lock>]

If I try the same thing on a PDF file it works fine. This is for version 3.1.1, thanks!

I can repeat the bug on both Mac OS X El Capitan and Debian 8, I can also repeat the error in version 3.1 and 3.0.

The file in question is here (yes I know there isn't any text I was just using it for testing):

Only PDF input is supported for now.

img2pdf does a good job at converting most JPEGs and PNGs to PDF. And yes, that's a really crappy error message, which I should fix.

Next release fixes the error message.

By the way, there should be no need to sudo ocrmypdf. You don't have to trust me with root access to your system.
