The package nautilus-dropbox install a library (libnautilus-dropbox.so) into: /usr/lib64/nautilus/extensions-3.0 so we can have the emblems! The problem is that it doesn't work because the library has the wrong permissions: -rwxr-x--- 1 root dropbox 44360 2 lug 19.38 libnautilus-dropbox.so while it should be: -rwxr-xr-x 1 root dropbox 44360 2 lug 19.39 libnautilus-dropbox.so to work properly!
