ErrorBox: Feature not available for users using GPG cannot be discarded

**Describe the bug**

Trying to apply a patch onto a new commit and getting the :

```Feature not available for users using GPG```

messagebox, which is fair enough I guess but the message box cannot be discarded and stick into the middle of the screen doing nothing much but feeling me guilty of using GPG (altho it's acutally ssh signed commit but that's another story/wording bug for antoher time) 😺.

**To Reproduce**
Steps to reproduce the behavior:

1. GPG your commit
2. Choose a patch from a commit
3. Press C-P
4. choose something to do of that patch
5. See error

**Expected behavior**
Esc to discard it i guess?
