Segmentation error when opening a folder (Oneiric)

If I open nautilus on "home" it's all right. Then when I try browsing to Documents folder (where I have simple 1 file and 3 other folders) it crashes and give me this error (in Italian):

Errore di segmentazione (core dump creato)

I think in english is "Segmentation error". I don't know how to find a dump for attaching in report...
