--- Comment #31 from Attila <bugs.kde.att...@online.de> --- I have changed the line to Exec=/bin/sleep 0.5; [ ! -z "%f" ] && kde-open5 "%f" When I click on "Open with File Manager" for the first time then nothing happens. That was the intention of [ ! -z "%f" ]. When I click on "Open with File Manager" for the second time then Dolphin shows the USB-Device without any error message but it doesn't solve the issue. In any case I have to click twice on "Open with File Manager" to see the USB-Device. By the way you are right. The call to mount a device doesn't happen in kde-open5. Questions: 1. What distribution do you have, because it seems to work on your machine? 2. Would you mind it to install Fedora 27 to give it a try? In this case you can easily commit and investigate this bug. I would appreciate any suggestion. -- You are receiving this mail because: You are watching all bug changes.
