After successfully moving my KMail4 to KMail5, I discovered the Ctrl+N shortcut threw up an error. "The key sequence 'Ctrl+N' is ambiguous. Use 'Configure Shortcuts' from the 'Settings' menu to solve the ambiguity. No action will be triggered." The shortcut settings had not been changed from the default setting and no other application was in conflict with it. After assigning nothing to the custom shortcut to New Message, the actual shortcut for New Message worked again. Attempts to reassign the shortcut back to the default setting threw up this error: "The 'Ctrl+N' key combination is already used by the New Message... action. Please select a different one." It is possible that remnants of the shortcuts in KMail4 are still being run, hence resulting in a conflict. Reproducible: Always Steps to Reproduce: 1. Tries to use (default setting) Ctrl+N in KMail5 after upgrading from KMail4 Actual Results: Error message given. Expected Results: New message window should have launched.
