Uninstalling and reinstalling worked for me but I had to setup all the accounts again.

Yes, you're right, uninstalling and reinstalling again fixes the issue.
Thank you very much.

In the past the app accidentally allowed the user to enter usernames and passwords containing line breaks. Newer app versions automatically strip line breaks when the user enters a username or password. We also added a check to make sure username and password in server settings never contain line breaks.
My assumption was that having a line break in the username or password will lead to a failure when checking server settings. So there won't be any existing accounts we have to fix during an upgrade. Apparently I was wrong. This crash also shows up for some beta users on Google Play.

Steps to reproduce:

1. Install K-9 Mail 6.803
2. Import the settings in issue_7855_settings.zip (dummy account containing line breaks in username of incoming and outgoing server settings)
3. Update to K-9 Mail 6.901 → App crashes during start
