Bugs in the xfce Thunar

I dont know what is notifying you of nautilus missing, but I doubt it is Docky. I believe we simply execute 'xdg-open trash://' and let xdg-open take care of the rest.

No, we use GLib to query the default handler for the file with a uri of trash:// Then we use GLib to launch whatever application is registered to open that uri. Thunar is heavily based on GLib / GIO, so I don't see why there would be a problem here.

I am having the same issue myself, Xubuntu 10.10
The "empty trash" command works like a charm, but the "open trash" command does exactly what the bug report says. A message pops up in notify-osd complaining

Error running: nautilus
Failed to execute child process
"nautilus" (No such file or directory)

This is an annoying bug, and as is proven with the "empty trash" command, totally unnecessary. I'm downloading the source and taking a look right now.

I think I have it figured out. The source file only references Nautilus once, and its in the "empty trash" command, which as we know, is functioning fine.
However, the "open trash" command makes references to the compile flags of the current system, specifically to the file manager.
So, if i'm not mistaken, this would mean that if nautilus was the file manager of the compile system, it would insert a reference to nautilus in the built file that is in the repository we install from.
I'm new to docky's code, and I'm not certain how to correct this (devs?)
