-- Information about the crash:
When I try to send or reply to an email, I get a strange error on any account - server error 5.7.8 Error, authentication failed - and the message stays in drafts. If I click on the draft, the program always crashes.

The crash can be reproduced every time.

-- Backtrace (Reduced):
