I fixed the bug with the group headers, and have moved on to this:

Looking at the code, it is not clear to me that I can fix the issue
with how applications like gwenview respond to getting multiple files.
 As best as I can tell each application on its own determines how to
respond to getting multiple file requests.  If I am right about this,
the bug will have to be fixed in each application individually, and is
outside the scope of what I can do.  Does anyone know if this is
correct?
