Comment 2 for bug 121796

I have just completed a dist-upgrade (and, indeed, xsane was updated), but GIMP still won't start from the right-click menu. I remind you that I GIMP starts normally from the Applications menu, and I can open the images with drag-and-drop just fine.

On the other hand, even if the GIMP would start, there's still the problem with the multiple (four, right now) entries in the right-click menu. I suspect the install scripts of the package have some kind of bug. (I didn't notice this with anything but GIMP, but it could also be a bug in whatever package manages the right-click menu. BTW, I'm using Gnome for everything.)

I've looked at the debug suggestions, but I can't find anything that applies to my case. The problem is that GIMP doesn't start only when I use the right-click menu of a file, so I can't attach any debuggers and such. GIMP starts normally when I start it myself, with only these warnings:

Executable not found: '/usr/lib/gimp/2.0/plug-ins/psd_save'
Executable not found: '/usr/lib/gimp/2.0/plug-ins/gifload'
Executable not found: '/usr/lib/gimp/2.0/plug-ins/tiff'
Executable not found: '/usr/lib/gimp/2.0/plug-ins/psd'
Executable not found: '/usr/lib/gimp/2.0/plug-ins/gif'

But it behaves the same for all kinds of files, including---which bugs me---JPEGs. I have started Nautilus from a command line so I can see its messages (I assume it's responsible for the right-click menu), and it doesn't display anything when I use the right-click menu. Nothing happens, apparently. I've checked the logs, too, I didn't see anything remotely relevant.

Any idea where Nautilus keeps it's right-click menu "settings", so I can check what's going on?
