yes, it's a bug. You get similar output with
darcs changes src/DOESNOTEXIST --summary --xml-output.

Every change to one of the parent directories is
considered a modification of the file at the moment,
even if the filename given is not tracked by darcs.

Of course this would be easy to fix for the given
invocation (just check the pristine directory).
If the to-patch option is also given it's not that
easy since to find out if src/DOESNOTEXIST existed
in the repo at the given point in the history.
This info will be stored in the filecache, so the
bug will be hopefully fixed sooner or later.

Best,
   Benedikt
