Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-18-generic x86_64
Distribution: Ubuntu 15.10

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

При удалении, создании и форматировании подключенного диска Plasma аварийно завершилась. Затем, все же, перезапустилась. Это уже не первый случай.

The crash can be reproduced sometimes.

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