dekko2 freezes reproducible on simple ASCII text mail
I get every morning from one of our Linux development hosts a simple ASCII text mail produced by our nightly build process. When I open this mail in Dekko2 (0.1.8-21b84), it tries to present this in a new screen but freezes. Only the Subject: is written on top of the screen. I could provide the mail in mbox format for debugging.
## Context
## Expected Behavior
The mail should be presented.
## Actual Behavior
The UI of Dekko2 freezes. Dekko2 must be restarted.
## Steps to Reproduce
1. Start Dekko2
2. Pick up (tap) the mail in question. The folder list is overwritten by the new screen. Dekko2 frezes.
