"ju" reported on IRC that browsing
https://nmbug.notmuchmail.org/nmweb/show/20160719094205.qmf5sjnja6crt5t3%40gotlib
crashed. The underlying issue is that python3 defaults to utf8
decoding files unless they are opened in binary mode. The file in
question (in the nmbug archive; it depends a bit on the routing the
message took) has
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 8bit
and some of it is not valid utf8.
