Bug 457367

Application: okular (22.04.1)

Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.18.13-200.fc36.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 36 (KDE Plasma)
DrKonqi: 5.25.3 [KCrashBackend]

-- Information about the crash:
Okular 22.04.1 is crashing only when opening a specific pdf file. I can't send the pdf file as it contains many private data, but as far as I can describe it, it's an invoice of a bought product from a shop. It contains text with different formating, picture and a table. It doesn't contain any electronic signature or any specific metadata as far as I can tell. I am sending a picture of some data collected by chromium browser of this pdf file under this link: https://imgur.com/0qaJkKi

The crash can be reproduced every time.

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