Hi, thanks for testing master.

I can semi reproduce this. For me it works the first time but a second call to
getpin fails.

And indeed this goes away with f4b5049c68a79d5e4faba06447db5440936cefeb~1

Looking at the code I don't see a reason for this. Maybe the dialog?
The code without the dialog 71b51e02cf20174ba7144765e985f7e889eaa429 also allows
me to repeatedly call getpin.

Werner: Any idea? I'm a bit clueless which change in the patch could have caused

This is really weird. Merely not adding the password reveal button to the hbox
'fixes' this problem. Therefore, I don't believe that the patch introduces the
bug, it merely makes it manifest itself.

I looked around in the related gtk bits, but I believe the problem might be in
the X server, or the asynchronous interaction with it. I don't believe it is
worth digging further into X.

Workaround committed in ad390f29.
