The requestPatterns in AbstractToken has value NULL
I just installed a clean distribution of the blog package and for some reason this install throws an error because of the return value in hasRequestPatterns() which returns TRUE when the requestPatterns value is NULL.
For this I'll upload a related patch on gerrit. Problem is how the value can be NULL. setRequestPatterns has typehinting for $requestPatterns being array, and isn't even called somewhere in the code. The property is protected, and has a default value of array(). Besides that: the setRequestPatterns() method is never called.
