Basically that's it. I have no idea what's wrong. I just uninstalled the KDE environment from my Ubuntu 9.04 installation, and now I can't open the Applications menu in my custom menu panel applet. In the main menu applet, the applications menu just doesn't appear. I haven't found anyone else with this problem, so I have no idea how to fix it. Any ideas?
Edit: Okay, so I just found a file in my .config folder called 'applications.menu', which is completely blank. Is this a problem?
