A vector full of NaNs apparently does not crash equations nor the low-pass filter (the other filtes being very close, I suppose it's the same for them). It sounds good :-)
And in the worst case (i.e. some plugins crashing) we could actually call the plugin only if the input vectors contain something else than NaNs, and return output scalars and vectors with NaNs without calling the plugin otherwise. That would mean forcing plugin output to NaNs when at least one input is pure-Nan, which sounds sensible to me...
