ManagementObjectSearcher (WMI) ignores metabase keys with ..

I am trying to list all the AppRoots for a given site, using WMI like this:

System.Collections.ArrayList alAppRoots = new
System.Collections.ArrayList();
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, new
ObjectQuery ("SELECT * FROM IIsDirectory where Name LIKE 'W3SVC/1/ROOT/%'"),
null);

ManagementObjectCollection appRoots = searcher.Get();
foreach(ManagementObject appRoot in appRoots)
{
if(appRoot.Properties["AppRoot"].Value != null)
{
string path = appRoot.Properties["AppRoot"].Value.ToString();
alAppRoots.Add(path);
}
}
return alAppRoots.ToArray(typeof(string)) as string[];


That works just fine, unless one of the AppRoots contains a null parent key.
You can easily create a null parent key using inetmgr. Say you have this
structure: /foo/bar/baz where /foo and /foo/bar have no corresponding
metbase keys. Create an AppRoot at /foo/bar/baz using inetmgr. The metabase
now shows /LM/W3SVC/1/Root/foo/bar/baz as an AppRoot, but also creates null
keys for /foo and /foo/bar in the process. WMI ignores /foo/bar/baz in the
above query.

Is this a WMI bug, or can I work around this?

as i used the following WQL-Command with WMITools (CIM Studio) i also get
the instance in the enumeration where the property "AppRoot" is "<empty>" (NULL):

SELECT * FROM IIsDirectory where Name LIKE 'W3SVC/%/ROOT%'

It exists no BUGs, that are all features.
