Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-43-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
I can go to several different applications in System Settings. The moment I open them, I see their form, the program hangs and all of the System Settings program crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted

Comment 1 Christoph Feck 2018-06-15 01:50:17 UTC

If this is still reproducible, could you please run systemsettings5 in Konsole and add the output from the abort message?

Comment 2 Andrew Dieffenbach 2018-06-15 13:34:31 UTC

Hello. This crash stopped reproducing after a reboot (or perhaps two).

I was worried initially because I thought I had rebooted after a sizeable update and this crash was occurring. I think what might of happened is I rebooted after an update only to a little later perform some additional updates.

At any rate, I believe that fixed these crashes. I'd say this bug can be closed as cannot reproduce.

Comment 3 Christoph Feck 2018-06-15 18:05:05 UTC

You probably updated either kernel or nvidia binary drivers. This requires a reboot, because nvidia kernel modules must match the installed driver, otherwise OpenGL does not work, and causes the abort message in Qt applications.
