Comment 8 for bug 1760170

It looks like WImageStore::getImage(const PixmapSource& source, double scaleFactor) {
Returns an invalid pointer.

Please try if a

if (source.isEmpty()) {
    return nullptr;
}

At the top of the function

And in:

QString makeSkinPath(const QString& relativePath) const {
        if (relatvePath.isEmpty() || relativePath.startsWith("/") || relativePath.contains(":")) {

Fixes the issue.
