 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:
