python-notmuch decoding error on a message

Subject: python-notmuch decoding error on a message

Date: Sun, 06 Nov 2011 22:16:03 -0000



From: Antoine Amarilli


The attached message makes python-notmuch crash when trying to access it (see
attached log).

I don't know if the encoding of Subject is valid or not, but it would probably
be better anyway to ignore decoding errors and return some approximation of
Subject instead of failing like this.

Any ideas?
