Bug 409345

Application: okular (1.7.2)

Qt Version: 5.13.0
Frameworks Version: 5.59.0
Operating System: Linux 5.0.13-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
The problem appears when Okular is run from Emacs for a pdf created by Pdflatex. Then scrolling is okay; Okular crashes if I try to open the main menu. Tried several times with the same result.

Removing the "--unique" option and/or the "#src:..." portion of the command line makes no difference. The crach doesn't appear when I open pdf files from Dolphin.

- Custom settings of the application:
Today I updated some parts of my system (Opensuse) including KDE. Perhaps some old versions of libraries may remain, I however was unable to locate them.

The crash can be reproduced every time.

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