#1428 Exception on exit under mono (Ubuntu 15.04)

[Vasya Pupkin]

Every time KeePass exits, I see an exception in terminal:

That is all Drawing and Forms, implying a mono issue, not KeePass.
Has it started happening all of a sudden?
Have you changed anything recently?

cheers, Paul

[Dominik Reichl]

I agree with Paul. As it can be seen from the stack trace, there's no KeePass code involved, thus this is a Mono bug.

Best regards,
Dominik
