Hello!

Unfortunately the QML Image can crash the whole application without being able to react, if a source is specified that has bad image data (which by specifying a URL is often not known ahead). The crash happens due it's assumed to be a SVG (while it's not) and the SVG parsing is seemingly not good enough guarded to handle errors, instead crashes.

The crash happened here on Qt 6.6.0 gcc_64 I installed fresh today. OS is Ubuntu 22.04.
Note: I can NOT reproduce the error in Qt 6.5.3 so seemingly this is a regression in Qt SVG module between Qt 6.5.3 - 6.6.0.

Minimal example

import QtQuick
import QtQuick.Window
import QtQuick.Controls
Window {
    width: 900
    height: 600
    visible: true

    Image {
        anchors.centerIn: parent
        source: "https://slashdot.org/slashdot-it.pl?op=discuss&id=23088195&smallembed=1"
    }
}

A copy of the "image" is attached to the issue (retrieved with wget <URL>).
Additional Qt SVG module is linked via CMakeLists.txt. Qt additional Image Formats are also installed.

Expectation

Yes, it's not a valid SVG image, or any image at all. Still, it should not produce a crash, but set a error state / mark as bad image via QImage::isNull=true.

In this case it is some URL that was returned by a RSS feed as a image attachment. User inputs for QML source can be <anything>.
