Nice work catching this!  When I was doing some testing
earlier, I had noticed that some data objects were not 
getting cleaned up after a save/reload - blender's version
of garbage collection.  At the time, I just put it in the
"Isn't That Strange!" category and didn't look into it further.

I went ahead and fixed these.  I figured if I was going to do
one, I might as well do them all.
