Bug 365058

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-28-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I was trying to move a file in my desktop. From one place, to another in desktop again. At the same time I was trying to open Chrome but I don't know if there is a relationship.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
