Bug 357180

Application: konsole (15.12.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.5-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Trying to select any text because after a recent Arch update I can only see very small white dots isntead of text.
- Unusual behavior I noticed:
The unreadably small (?) text. I can't even resize it. Trying to select anything with the mouse causes this segfault. See attached screencast.
- Custom settings of the application:
None that I know of.

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
