Bug 395158

Application: okular (1.4.2)

Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.13.0-43-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
This might be an obscure one, but anyway:

- What I was doing when the application crashed:
1. Started Okular
2. Chooe File → Open
3. Opened a PDF (see the attachment)
4. Chose Show → Presentation
5. Browsed to the end of the document in Presentation mode
6. Exited Presentation mode
7. Just browsed the menu bar selections randomly with the cursor (to reproduce a freeze)
8. Tried to close Okular with Alt-F4.
9. Crashed.

I have frequent trouble with this PDF document (freezes the system), but I'll file another report for that in case it's unrelated.

Attaching the PDF I opened.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Okular (okular), signal: Aborted
