Comment 7 for bug 844983

swedpool, you should use the patch command, see

man patch

for the correct options to use.

Typically, you should save the file included in comment #3 to any location you like (e.g. "path-to-the-patch-file"); then chdir into the directory containing your module_gnome.c, and issue the command

patch < path-to-the-patch-file/desktopnova-ubuntu-11.10.patch

Then you can compile the program again and it should work (sorry if I cannot be more detailed now, but I don't have access to my desktopnova installation at the moment)
