Sentry Crash Report:

Description p92 2015-05-29 11:06:52 UTC 
Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-lowlatency x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I have activated background desktop disporama since installation with one folder and this worked ok. 
I wanted to add another folder to the diaporama so I selected it and then clicked on apply
- Unusual behavior I noticed:
plasma waits some seconds then crashed and restarted
upon restart my new disporamafolder is not added..
I can reproduce at will - it is impossible for me to change the diaporama folders
- Custom settings of the application:
the disporama folders are on an nfs folder on a synology diskstation and the synology has created an index on each folder called @eaDir

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
