Pointless warning canceling a new relation without information

[skyper]

What steps will reproduce the problem?

1. create a new relation or clone an existing one
2. do nothing in the relation editor except:
3. press ESC (twice) or click on "cancel"

What is the expected result?

The window is directly closed without any warning.

What happens instead?

A warning window to prevent loosing changes.

Please provide any additional information below. Attach a screenshot if possible.

As there was no information added the warning is pointless and annoying. This effect not does accure if you open an relation manager of an existing (created in advanced) relation and cancel(close) it without change. Please adopt this behaviour. Thanks
