From Laurens Voerman, "while debugging ImageSequence I had a crash, due to the very large frametimes caused by halting the program. The problem is that when the frame time exceeds the length of the entire image sequence, a looping  sequence will try to read it's _imageDataList beyond its size. fix attached for  src/osg/ImageSequence.cpp"
