FP4: K9 + OpenKeyChain - cannot connect to crypto provider

Hello!

I use K9 for email and my mails are encrypted on mailbox.org. I can decrypt my mails on the phone using OpenKeyChain. But when I want to send an email from K9 ist says ‘cannot connect to crypto provider’. When I retry, K9 crashes. I have to switch off encryption in K9 settings to send an email.

Is that a known issue and has anybody a workaround to fix it?

Thanks in advanced.
