I just ran a test with gwenview. It just spits out junk :(.

I didn't get the nepomuk errors, but I did get some debug notices.

gwenview(29917)/kdeui (kdelibs): Attempt to use QAction "edit_redo" with
KXMLGUIFactory! 
gwenview(29917)/kdeui (kdelibs): Attempt to use QAction "edit_undo" with
KXMLGUIFactory! 
gwenview(29917) Gwenview::ViewMainPagePrivate::setCurrentView: No index
found for current view

It would be nice if it ran more cleanly.

Put an '&' at the end to run the command in the background, then you can
close the terminal.

gwenview filename.jpg 2>/dev/null &

This will also work for within a script if you want the script to move on
directly after launching gwenview.

Alternatively, you can use <alt>-<F2> to bring up a launcher and put your
command in that.

gwenview *png

That will run gwenview disassociated from a terminal, so there is no
terminal to close and there is no terminal to recieve the debug messages.

ciao,
