Printing XML under Linux crashes the App

[ingmar42]

Under Linux it is not possible to print the XML part. When I select "Print XML" and select a printer, the App does not print and crashes with a Memory Exception (in my german Linux the error is "Speicherzugriffsfehler").
I have tested under Kubuntu 24.04, Debian 11 and Debian 12.

Under MacOS (14.7.2) the printing option is grayed out for XRechnung. It is likely the same underlying problem.
I just wanted to open an issue requesting to fix this issue when I saw your case.
