Delete dialog for contacts and messages getting unfocussed once we use keyboard shortcut "DELETE""

[yuvarajgogoi]

Step to reproduce

1. select any mail or a contact
2. press "DELETE" Keyboard key( not the DELETE button on KH with which this scenario works fine)
3. A Dialog appears asking for confirmation.
4. Press delete.

Issue is delete doesn't happen, because the Dialog is unfocussed .

Tested in Debain and is always reproducible. With Windows 7 its working fine.
