[Scribus] difficulties with "collect for output" function

[Sunil Joshi]

When I try to run the "collect for output" function, it only exports 
the .sla file, and not the image files associated with the document.  
In the xterm window, I get this error:

> cp: copying multiple files, but last argument `600-3.tif' is not a 
> directory
> Try `cp --help' for more information.
> cp: copying multiple files, but last argument `1/leafwatermark2.jpg' 
> is not a directory
> Try `cp --help' for more information.

I have observed that in the collect for output window, the "File type" 
is greyed out with "directories" showing.  I wonder why I am unable to 
change the file type, and if that is what is causing the error message.
