Encoding errors in Gmail?

[Caleb Rogers]

This is super weird, you're having an identical issue to me, 
including from a sendgrid address:

ERROR: UID 126179 
(<ZF3lf1bGTw-Ct-Y9A15WlqUQ3BukrDdPHg-173.82.166.30 at ismtpd0003p1iad1.sendgrid.net>) 
has defects preventing it from being processed!
  UnicodeEncodeError: 'ascii' codec can't encode characters in 
  position 434-435: ordinal not in range(128)

I've been meaning to post on stackoverflow or here about it but 
just haven't gotten around to it

It prevents me from keeping offlineimap running continously 
because it causes a crash.

I also wasn't able to find the offending email on my gmail server 
anywhere, at least not using gmail's search tools (or other 
applications), because if I could I'd just delete it and move on.
