From Wojciech Lewandowski, "osgSim::BlinkSequence has sequenceGroup unitialized by default (=NULL ref_ptr). By looking at the code I figured out that unset sequenceGroup is completely correct and thus allowed.

Browse Source 
But writing BlinkSequence with empty sequence group caused a crash when IVE was accessing baseTime from NULL address.
 
Atttached is a fix for this situation.
