Hi list,

I'm on TDE R14.0.4, Mint 18 installation. If I insert any USB memory stick I get 
two icons on the desktop and two pop-up windows notifying me "a new medium has 
been detected". E.g. one icon gives hint "/dev/sdd", the other one "/dev/sdd1". 
One of both mounts device, the other one states "unable to open device" even if 
I press it first. The correct message is:

========= snip ===============
Unable to mount this device.
Potential reasons include:
Improper device and/or user privilege level
Corrupt data on storage device
Technical details:
org.freedesktop.DBus.Error.UnknownMethod:
No such interface 'org.freedesktop.UDisks2.Filesystem' on
object at path /org/freedesktop/UDisks2/block_devices/sdd
========= snip ===============

Anyone any idea where to look for this problem? Even an USB printer opens a 
notifier window asking what to do with the removable device.

I already moved away the .trinity folder and logged in again without success.

Any help is appreciated
Gerhard

PS: I could try to chose 'do nothing' and check the 'always do this for this 
type of media' checkbox for the non working device but I fear, that afterwards 
even the correct working notification will not display any longer.
