By harmless do you mean that 
 a) The files are checked and guaranteed to be byte-wise identical - not just 
same name?
 b) the file won't be deleted unless both the providing packages are gc-ed 
(presumably via some reference counting facility?)
 c) both
 d) YMMV

By annoying do you mean
 a) it litters up the screen with un-necessary warnings
 b) it causes package installation to run substantially slower
 c) both
 c) foo

Thanks,
