From Farshid Lashkari, "Attached is a simple fix to osg::Sequence that allows it to load properly with the serializer formats (osgt/osgb). The problem was that the internal _nrepsRemain member was not being initialized properly if the number of repeats was equal to the default value of -1. When the number of repeats is explicitly set using setNumRepeats(), _nrepsRemain is set to the same value. However, in the constructor of osg::Sequence, it was not being initialized to the same value as _nreps. This fix simply changes the initial value of _nrepsRemain to the same as _nreps."
