            Bug ID: 361518
           Summary: playing with add widget plasma 5.6.1 crash
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED

Application: plasmashell (5.6.90)

Qt Version: 5.6.1
Frameworks Version: 5.21.0
Operating System: Linux 4.6.0-rc2-2.g7f2acea-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Since I've lost again the widget on my desktop (Thermal and folder view) I was
trying to add them again.
Once both of them were placed, I decide to click on remove bumblebee indicator,
and then continue to scroll the list)
 suddently everything has gone away, and I was notified of plasma crash.

Nvidia is 364.12 (.run installed), kernel is 4.6.0-rc2, qt is 5.6.1
openSUSE Tumbleweed + kde repositories used qt56, kua, kuf

Double HiDPI screen used (dpi setup hard on nvidia device configuration to
168px)
Was happening just after opening a session.

The crash can be reproduced sometimes.

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