Dear Maintainer, At start gwenview reports about same shortcut (shift + del) for two actions: delete and cut. Indeed they're default shortcuts.
This is also happening for me. Whenever I start Gwenview, I get a message box: "There are two actions (Cut, Delete) that want to use the same shortcut (Shift+Del). This is most probably a bug. Please report it in bugs.kde.org" It's minor bug as clicking Ok in the message box takes you to Gwenview, but it's annoying. It looks like this was already reported and fixed upstream https://bugs.kde.org/show_bug.cgi?id=347373
Looks like this bug got resolved. Had the same issue before, but it got fixed in the latest (4:17.08.3-1) version of the package.
