Trash and Root folder misassociated in gnome need help

Hi all, i have aproblem i posted in a different thread but i was much to vague with my question, When logged as my user on my box i can't access the trash folder and home dir folder on my desktop, i saw that under the open with other applications selection that mplayer was there, after checking associate application i saw that the default action was set to mplayer not Custom, i changed it back but i still get no response from clicking on my Trash or home dir icons except the open app sound. When i log as root and start gnome i can open trash and my home dir fine. I feel it has something to do with the file association, can anybody give me a idea on how to make it better :) using slack9, dropline gnome. thnxs
