SVN commit 552811 by staikos:

two patches that got a bit intertwined due to offline work.

1) Make vectors initialize to NOPOINT instead of 0
BUG: 128436
2) Fix a very tricky deadlock in objects iwth providers, especially plugins.
There is more to be done here.  The fix only applies to vectors at the moment.
