-- Information about the crash:
- What I was doing when the application crashed:
Click to download a pdf document from Google Drive (in Firefox). Rather than
save the pdf, select Open and select Okular from list of apps. Okular opens but
immediately crash again. Tried multiple times.

The crash can be reproduced every time.
