This thread went pretty far afield from the actual problem, with many of the exchanges focused on OpenNI Tracker when the actual issue had nothing to do with that plugin. So, for the benefit of any reading this in the future, I have removed all but the first and last posts so that the initial problem statement and the solution remains.
I've also changed the generic subject line "ARM 3.2 Crashes" to "Crashes Because of Value Delay Line Actor Using Strings" so that people will immediately know what the source of the problem was.
Best Wishes,
Mark
