It looks like you didn't CC him so if he's not subscribed to
evolution's PTS, chances are that he missed your message.

FWIW, I experience a very similar crash when clicking on the button
with the down arrow that is supposed to show a list of the programs
that are able to display the attachment (PDF in my case).  I can
confirm that applying the upstream commit you quoted (811a6df) fixes
the problem entirely.

Here's my backtrace:
