[Bf-committers] Camera motion blur bug + fix

[Ton Roosendaal]

Hi,

That call will break other things (forgot which, no time now...). I'm  
aware of the issue, there are more side effects (like python lens  
animations). It's more of a design error, parts of pipeline flow for  
camera/scene stuff has to be tweaked for a real solution.
