In Ubuntu 15.04 I'm using the 2 filemanagers Nemo and Krusader. My smartphone is usb-connected and already mounted, and it is displayed in Nemo. But in Krusader it is not. Why? How can I solve this?

Thank You for all answers!

After some investigations I found out, that this bug is konfirmed and was not in earlier versions of krusader: https://bugs.kde.org/show_bug.cgi?id=325649.

EDIT// After posting in ubuntuusers.de/forum I was given a solution: Deaktivating automount for media, so the android is not active in Nemo. Them type "mtp:/" (without "") into the adressbar of Krusader and - voilà - android is displayed by given name.
I was told that MTP-Connections only function in 1 instance - either Nemo or Krusader in this case.
