Bug 404078

Application: ark (17.12.3)

Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.12.14-lp150.12.28-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- What I was doing when the application crashed:
I had a PDF open in full screen. I switched to the full screen by doing (Left) Ctrl + (Left) Shift + P. Browsed through a few slides. Pressed Escape to close the full screen. Switched windows, returned to the Okular window, and pressed that same combination of the keys to return to full screen. That is when the crashed happened.

This bug happened twice with this same PDF file. I have been able to reproduce it with another two PDF files from different sources.

The crash can be reproduced every time.

-- Backtrace:
Application: Ark (ark), signal: Aborted
