Created attachment 105041 [details] Dolphin displays on the panel 5 loop devices (“Dispositivo de bucle”), which correspond to 3 Snap applications. I'm using KDE Neon (Ubuntu 16.04) with Plasma 5.9.4. As you know, Snap application packages, for security, mount a read-only virtual drive to store each application (these are mounted in the "/snap" directory). These virtual drives appear in the Dolphin places panel ("Devices" section), labeled "Loop device", each time a Snap application is installed. That is, if I have 5 Snap applications installed, at least 6 units "Loop device" appear on the Dolphin panel (5 apps + the "core"). This seems like a very insignificant "bug", however it is quite annoying, since "loop devices" often appear constantly, even if hidden from the panel. To fix this, ideally, Dolphin would not display on the places panel the drives mounted in the “/snap” directory.

I can confirm on Arch and neon dev unstable.
