[Gambas-bugtracker] Bug #2842: Program doesn't start if gb.qt5.webview and gb.qt5.webkit are in the Project

Claus DIETRICH reported a new bug.

Summary
-------

Program doesn't start if gb.qt5.webview and gb.qt5.webkit are in the Project

Type             : Bug
Priority         : Medium
Gambas version   : 3.18
Product          : QT5 component


Description
-----------

We had a request in German Gambas Club where a program didn't start and showed an error message in the IDE-console: "ERROR: #63: '&1.&2' is incorrectly overridden in class '&3'|WebSettings|Fonts|WebSettings".
I boiled it down to the attached very small demo to show that this problem occurs, when gb.qt5.webview and gb.qt5.webkit are part of the same project. The same happens in the master version.
Best regards
Claus
