Trashbin applet error

["Antonio M" <antonio montagnani gmail com>]

on one of my system (my main home system) when I log in I get a
message saying that there is some error in applet of trashbin loading
OOefd: or something like this and asking if I waant to delete applet
loading from my configuration.Of course I say no and everything runs.
On same system I can't insert trashbin on my application bar. I
suppose that the two isssues are connected....
Any help??

Tnx
