how to filter for empty folders (size zero) (bug?)

[iwant2know]

i have created a custom filter,
in General tab, Include: "*" and Apply for "Files and Folders"
in Attr/Size tab I have ticked "File size" Min: 0 and Max: 0

the filter works only for files not for folders!
can anyone confirm a bug here?

ticking only "not older than" 1 Day works for both, files and folders.
