Description Samantha McVey 2017-10-15 12:06:52 UTC

Application: systemsettings5 (5.11.0)

Qt Version: 5.9.2
Frameworks Version: 5.38.0
Operating System: Linux 4.12.0-sabayon x86_64
Distribution: "Sabayon Linux amd64 17.11"

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

Typing things into the search box

- Unusual behavior I noticed:

The search box text was pixelated. (Looked scaled up, while the rest of the application looked fine).

- Custom settings of the application:

I had a HiDPI screen, and have scaling set to:

Force fonts DPI: 154
Screen scaling: 1.6

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault

New crash information added by DrKonqi

systemsettings5 (5.11.1) using Qt 5.9.2

- What I was doing when the application crashed:
Searching for a term in System Settings makes the applications crash if the term searched cannot be found.
For instance, if I search for "Icons" or "Colors" everything works fine, while if I search for "Vault" the program crashes.
It doesn't happen everytime.
