 (Compiled from sources)
Qt Version: 5.15.12
Frameworks Version: 5.113.0
Operating System: Linux 6.6.13-gentoo-a x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
I was signing a pdf form. Right after signing, Okular crashed. (The signed pdf was properly generated, though.) In all recent times I used Okular to sign a pdf, it did not crash. The only thing that was different now is that I had mistyped my smartcard pin code once.

The reporter is unsure if this crash is reproducible.

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