Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:  Seems similar/identical to 350301 but I cannot figure out how to actually report that.  The "+suggest this is similar report (or whatever) button seems to do nothing only leading to an endless loop. 
SO... Partitioned USB stick using KDE partition manager, Baloo crashed then Plasma immediately reported as crash.  Both seemed to restart.
Good luck with this.  This reporting method is very unclear to me, a noob, but seriously, many buttons or options that don't seem to actually do anthing.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
