unexpected behavior of escape button in validator

[Klumbumbus]

What steps will reproduce the problem?

1. validate data
2. in the validator dialog select a group of erros (e.g. "warnings") or a folder in there.
3. press ignore
4. a window pops up, which asks "Ignore whole group or individual elements?"
5. press ESC to cancel the operation

What is the expected result?

the window closes and nothing gets ignored.

What happens instead?

all the selected errors get ignored.
