I found another occurence and I fixed it too. I agree that a test case would be 
nice but I don't have a test file. If possible, please attach it here. 
Alternatively I could write some code that goes through our test files hoping 
to hit such an case.

> Attribute dictionaries attached to a structure element may be either direct 
> or references.  getAttributes() handles the direct case but ignores object 
> references without error messages.  This can also lead to invalid revision 
> numbers attached to the attribute dictionaries it does handle properly.
>  
> The fix would be to add another branch to the iteration loop in 
> PDStructureElement.getAttributes(), to handle object references.
