I have a hardware token from SafeNet which I'm using to sign PDF documents. I'd
like to use this with Okular, too, and I got some progress to the point I can
sign PDF documents with LibreOffice or pdfsig. When I try do to this with
Okular, it crashes on configuring the PDF backend.


STEPS TO REPRODUCE
1. With your SafeNet token attached, go to Settings -> Configure Backends...
2. Select PDF from sidebar
3. A popup asking you to insert the password for the token will appear.

OBSERVED RESULT
Inserting a correct password or even pressing Cancel will crash the app with
the following error:

Thread 1 "okular" received signal SIGSEGV, Segmentation fault.
0x00007ffff71a434f in QWidgetPrivate::drawWidget(QPaintDevice*, QRegion const&,
QPoint const&, QFlags<QWidgetPrivate::DrawWidgetFlag>, QPainter*,
QWidgetRepaintManager*) () from /usr/lib/libQt5Widgets.so.5

EXPECTED RESULT
The app should not crash
