    I'm not sure if this is the correct approach either.
    
    When i'm looking at file.cpp (in kio/src/ioslaves/file/file.cpp) then this very same thing is done. So from a mac/linux perspective, this aproach is fine.
    
    However, we also have a specific windows implementation "file_win.cpp" which is in fact filling the username and group via a slightly different mechanism.
    
    On Linux/Mac: we use stat calls. Aka, we are completely in control.
    On Windows we (why?) use QDirIterator. Each entry is then represented as a QFileInfo which in turn is being used to get the details from inclusing user/group.
    
    I can see a few approaches that could work:
    1. This version where windows is just out of luck.
    2. If windows is used, contruct a QFileInfo and get the user/group from there. Windows users will then have more stat calls in this function. Something we should try to prevent.
    3. This version and add a new constructor that takes a QFileInfo object - my preference.
    
    ... I think we need to wait for David' opinion on this. If David is OK with point 3 then i will create a patch + test and send a RR for it.
