What happens here is that the <c-o> handler tries to throw the error "Feature not available for users using GPG", but nobody catches it, and so it bubbles up all the way into gocui, which panics seeing the error.

Which means that there are two potential solutions to this bug:

1. Make it actually work
2. Make it show the error message that the command is not supported, without crashing

The first of these is tricky and requires more work (see here; I'm not really sure I understand that comment though...).

The second is much easier, all it takes is a call to c.Error(err) at the appropriate point in the call chain. A good place might be in MenuController.press(). However, an even better fix would be to do #3491, this would solve it once and for all everywhere.

Closing as this should be solved by #3502 (although I didn't retest this to verify).

[chmouel]

correct, it doesn't crash anymore ! altho it doesn't allow it fyi
