Are you talking about obsolete packages that are still in the distribution and testing in particular, 
i.e. iwidgets and itk3.1? The dependencies of those packages say 8.3. *That* is the bug. Either 
they do and are not working (since I have 8.3 installed by the System Information sent with the bug) 
or they don't which means the dependencies are wrong.  (However, as an extra bit of info, I believe 
the machine that I tested that on has 8.5 also installed and so I suspect something else is weird here.)
