ValueError on encode

[C-gotoh]

I'm using qr-backup v1.1.3 installed via aur.
Tried to encode a simple file to test this qr-backup README.md but got an error:

Traceback (most recent call last):

That's new.

Should be fixed in master (73f5bc2). I think this was triggered by a PIL update, but it was really faulty code to begin with.
