Created attachment 103357 [details] ambiguous popup box Fresh update from openSUSE. Kontact 5.3.0. Defined shortcut Ctrl-n in kmail for new message. In Kontact, with mail selected. Ctrl-n results in a popup box saying the shortcut is ambiguous, and to edit the Shortcuts. The shourtcuts (in Kontact) look right to me. The shortcut is not ambiguous in the context.

I can confirm this problem with kontact 5.5.1 compiled from sources.
This bug is still valid in 5.6.3 on Debian testing (17.08.3 bundle). Similar to bug #235224 and probably a duplicate of bug #354941.
