SUMMARY
Sending a message crashes, resulting in a load of 
"org.kde.pim.kmail: Danger, using an event loop, this should no longer be happening!"
errors.
This happens when sending from a protonmail account to a protonmail account. Sending to, e.g. GMail gives "connection refused", and I don't have any other mail accounts to test sending from.

STEPS TO REPRODUCE
1. Send an email from a protonmail account to another protonmmail account

OBSERVED RESULT
Crash, with error:
org.kde.pim.kmail: Danger, using an event loop, this should no longer be happening!
[1]    11591 alarm      kontact

EXPECTED RESULT
Email sends as usual
