SUMMARY In dolphin with the "Start a slideshow" service enabled. STEPS TO REPRODUCE 1. Open a folder without any images 2. Right click OBSERVED RESULT "Start a slideshow" is present in the context menu EXPECTED RESULT "Start a slideshow" is not present in the context menu. This affects also files selected. Fixing this bug involves replacing the slideshow.desktop service file by an implementation of KAbstractFileItemActionPlugin (like ark's compress).
