Whenever a CVS file is not found on the server an error occurs. 
Now it is possible that the file was moved out of or into the Attic. 

In this case, the patched code looks for the file also in the Attic (if the file was not found outside the Attic) of outside the Attic (if the file could not be found within the Attic)

As I do not have write access to the reviewboard repository, the contents of the review cannot be commited by me. 
A member of the project has to merge the changeset into the file. Thanks.

I tested both ways within our development project
