Mail crashes on start

[ReinerKnudsen]

Since I installed El Capitan Beta 3 I can't start the Mail app. I do NOT use any Exchange account. I get an error message

When I click "Crash" or "Continue" the app will crash.

"Show Details" provides the following details:

Exception Name: NSUnknownKeyException

Description: [<HeadersEditor 0x7f828c642a90> valueForUndefinedKey:]: this class is not key value coding-compliant for the key _documentEditor.

User Info: {

NSTargetObjectUserInfoKey = "<HeadersEditor: 0x7f828c642a90>";

NSUnknownUserInfoKey = "_documentEditor";

}

I had issues with GPGMail when I installed Beta 3 but I think I completely uninstalled it (via AppDelete).

Can someone help me figure out what the problem is?

Btw: I installed Postbox which runs perfectly.

Thanks for your help.

Did you try uninstalling it following their instructions?
