Hi all,

I discovered that gb.qt5.webview doesn't run on a Debian 12 on Raspberry Pi.

I discovered it using Gambas 3.19.6. So, I installed master version (today) and tested.

Seems that both qt5 and qt6 webview do not work. Note that the gbt3.webview does work.

Attached source archive to reproduce. In the Data folder is the system info of the Pi and of some amd64 systems where qt5.webview works just fine.

Screenshot shows qt5 output when run.

Screenshot shows qt6 output when run.

A bug or what is happening here?

Anyone able to test on a Pi running Debian 13 maybe?
