Bug 511416

Application: okular (23.08.5)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.14.0-34-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.3 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
Because I have a nssdb at the default location, it prompts me for the NSS Certificate DB password. Whether I enter the password and click "OK, or click "Cancel", Okular crashes.

Going to   Settings > Configure Backends > PDF, Okular ties to open a certificate database in the location of the firefox profile, after entering the passphrase, Okular crashes. Copying the files to the default location of ~/pki/nssdb also crashes. Canceling the popup that asks for the passphrase also crashes.

The console just says:

QWidget::repaint: Recursive repaint detected
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = okular path = /usr/bin pid = 14810

The crash can be reproduced every time.

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