From Sukender, "I had some conflicts when updating but they seem resolved now. Attached files (four files) are against rev. 11200. Changelog:

Browse Source 
- Replaced exceptions with assert() or OSG_NOTIFY
- Replaced osg::notify() with OSG_NOTIFY
- Changed braces and tabs to fit OSG coding convention
- Cleaned a few things in code (names, added deallocations upon error)"
