Thanks Nicolas, much appreciated!

 From what I can gather, affected applications tended to not start at 
all, or crashed almost immediately. Hopefully those initial teething 
issues are now resolved.

Nvidia have just released an update, 367.44, so I'll try to get builds 
of that done for the testing repo too - will probably be over the 
weekend. I don't expect any major changes though as the changelog 
doesn't mention anything GLVND related.
