Sorry for the previous comment, typed the wrong button and couldn't correct it...
Please, don't close this bug report, Gnomenu was working until I had done some tests and uninstalled xfce4-session. I reinstalled it, but simply it doesn't work anymore. The last time this problem occured, it was solved by reinstalling python-gmenu, but now it doesn't help. I purged and reinstalled all dependencies, but still no luck. I created a new user and the problem didn't go away.
