Error caused by BinaryDistributionModule

[GoogleCodeExporter]

Not every binary does this, and when refreshing it does get the images, but 
something is going wrong here when requesting a page containing images:

Error message
System.Collections.Generic.KeyNotFoundException: The given key was not present 
in the dictionary.

Judging by the stack trace it seems to go wrong when instantiating the 
BinaryProvider property of the BinaryFactory. Could it be something in your DI? 
Or maybe you are using a custom PublicationResolver?

I don't have a custom PublicationResolver running. 
This is only happening when there are no Binaries in the BinaryData folder and 
visiting the website for the first time. After refreshing it works again. So it 
happens when there are a couple of binaries (images) on a page that need 
retrieving from the database.

We think it is caused by concurrent access to the _binaryProvider field in the 
BinaryProvider getter property in BinaryFactory.
