Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

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

I opened the Get New Looks window from the Look and Feel section and then I first closed the System Settings window and then the Get New Looks window. Next time when I opened the System Settings it crashed,
I tried it again and I got the same result.

The crash can be reproduced every time.

Comment 1 Christoph Feck 2017-02-01 22:58:18 UTC 
GHNS dialog needs to be modal to the main window, otherwise it can be closed while the GHNS dialog is still open.
Comment 2 Kai Uwe Broulik 2017-02-02 13:04:56 UTC 
I changed the show() call to open() which makes it modal but that doesn't prevent closing the System Settings window. The same bug also happens in the desktop theme KCM which has been like this forever.

I think the dialog needs to be parented to the KCM or the window so it just closes when you close the System Settings window. There doesn't seem to be a way to access the window the QML ConfigModule is in, though.
