                OS: Linux
            Status: REPORTED
          Keywords: drkonqi

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 opened the form pdf from
https://formulare.bmf.gv.at/service/formulare/inter-Steuern/pdfs/9999/E30.pdf
activated to show the form fields, selected some text from a different browser
window with the mouse,
then clicked into the first input field and middle-clicked to paste the text ->
crash

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
