I got the following message (after brand new install of Mint KDE 18.0) when clicking on a jpg file to open and view a photo. Copied and pasted: 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 My pc is a Dell Opti-Plex 760 with 8 gigs mem and an 128gb SSD.
