That reeks that the patch doesn't do anything. I wonder, looking at the code:

QStringList QStandardPaths::standardLocations(StandardLocation type)
{
    QStringList dirs;

    if (type == GenericDataLocation || type == DataLocation || type == GenericCacheLocation || type == CacheLocation) {
        const QString path = macLocation(type, kOnAppropriateDisk);
        if (!path.isEmpty())
            dirs.append(path);
    }

    if (type == GenericDataLocation) {
        dirs.append(xdgDataDirs());
    }

    if (type == DataLocation) {
        QStringList xdgDirs = xdgDataDirs();
        for (int i = 0; i < xdgDirs.count(); ++i) {
            appendOrganizationAndApp(xdgDirs[i]);
        }
        dirs.append(xdgDirs);

        CFBundleRef mainBundle = CFBundleGetMainBundle();
        if (mainBundle) {

I'm tempted to say that the 1st, conditional invocation of xdgDataDirs() should come *before* the call to macLocation(), no?

Also, side-ways related: why does Qt only look in /System/Library/Fonts, and not first in /Library/Fonts as the OS does?
