Description of problem:

Nautilus (files).  

Step 1
Clicking "+Other Locations" presents a list of partitions that I can mount.
I choose one, the spinning "wait" is presented, and no activity takes place.
I get the feeling that Nautilus is waiting on a lock so that a mount can be performed.  

Step 2
If I cancel, and retry,  No partitions are listed when "+Other Loations" is reselected.  It appears to require a reboot to return to Step 1 

As well, the same problem is present with the liveworkstation iso version
