Steps to reproduce the error

• I have no clue really, I'm just starting to play around with neomutt+notmuch and I deleted a bunch of emails, and as a newb to offlineimap and CLI mail handling it would take me a while to dig into it, but regardless it feels like a pretty silly coding error and that this error message should handle ... the error and print it. Or if this function really shouldn't receieve a bytes objects, then handle the problem further up in order to print a helpful error message.

This legacy project works with py2 only. There's offlineimap3 for python3.
