You do know that you don't need to use a different computer to run GNOME-based apps, right?
All I'm really using is GNOME's file manager, Nautilus, which I expected not to work for this on account of either its gvfs dependencies, or the underlying system being broken anyway (KDE's mount device notification does not work). But I tried it and it can actually access the photos on my camera, even under KDE, and even though Dolphin cannot.
I cannot install Digikam right now due to conflicts but I'll keep it in mind for later as lens correction profiles could be nice. I have also tested Clementine and although treating the library as a play-list is a bit weird it works. Too bad Debian installs KDE's broken standard application by default.
