I checked commit comments, but couldn't find anything related. Checked a
bit closer now: my best _guess_ is, it's related to the following
simgear change:

Specifically, the diff contains:
> SGReaderWriterXML::readNode(const std::string& fileName,
> {
> + std::string fileName = osgDB::findDataFile(name, options);
> +
> osg::Node *result=0;
> try {

The XML reader relies on osgDB to resolve paths now. If
osgDB::findDataFile cannot find the file, it returns "", in which case
SGModelLib::findDataFile cannot search any additional directories.
So, maybe osgDB::findDataFile doesn't know about extra directories,
while SGModelLib::findDataFile was fg-aircraft aware. Not sure why the
change was applied in the first place.
Again, I haven't tested - it just looks plausible and somehow related.
Maybe you or Mathias can investigate if that's what triggered it and
whether anything else may still be broken now.
cheers,
Thorsten
