ROX-Filer shows red Xs for the toolbar icons

When I log out and log back in again, the filer shows red Xs for the toolbar icons and other things don't work well

The filer needs to be run using the 'rox' shell script, not by running the ROX-Filer binary directly. Some systems try to implement a primitive form of session management (without using XSMP, which the filer supports) and fail to restart it correctly.
