Crashes When Printing

I have this as well on Big Sur 11.1 Beta (20C5048k).

To reproduce:
- select a message in the message list - hit CMD+P - crash

This bug seems to be a duplicate of #2650.
The committed fix is working for me with Version 1.14 (5739) on Big Sur 11.1 Beta (20C5048k).

How do I get the 5739 build!? I have been printing emails by locating them in the Finder and opening them with a separate app. Would love to use the fix.

There is R5740 now too. Both 5739 and 5740 are rock solid for me.

Hold down the option key when clicking on check for update

Checking for updates does not work for me - with or without option key pressed (Dialog "Error Checking for Update / Malformed server response."). No idea if this is related to the test builds (I get this with both, 5739 and 5740) or the update server.

5740 works like a champ. Thanks!

I did a lot of code changes in recent releases leading to a number of new bugs and therefore I did not make it available on the test release branch (a surprising number of people fetch those regularly), but I think I'm close to being able to getting back on the test release branch (the ones fetched when holding down the option key). The r5741 version includes a fix for the only known frequent crash bug (for some users).

I thought I had fixed the “malformed server response” issue. I'll look into that again.
