            Bug ID: 357834
           Summary: Crash on inserting USB stick with EFI partition on it
           Product: plasmashell
           Version: 5.5.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: crigu...@gmail.com
                CC: bhus...@gmail.com, plasma-b...@kde.org

Application: plasmashell (5.5.2)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-5-default x86_64
Distribution: "openSUSE Tumbleweed (20151124) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I had just inserted a USB stick with a small EFI partition on it (rEFInd boot
manager).
The "USB inserted" dialog didn't come up, so I opened the tray menu and
selected the device notifier tab, which showed nothing.
Upon closing the pop-up window I noticed that the whole tray had become
inactive (it was greyed out) and shortly after plasma crashed.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
