Is this on a 64bit machine ?

Yes it is.  I'm going to jailbreak the ipod in a different way to see if that
has any effect upon the ssh mount.

I suspect what you are seeing is 

#define GET_FILE_HANDLE(fi)     (GUINT_TO_POINTER ((guint) (fi)->fh))
#define SET_FILE_HANDLE(fi, fh) ((fi)->fh = (guint64) GPOINTER_TO_UINT (fh))

being not 64-bit clean

Jesse, please try with gvfs-0.2.3-2.fc9 when it finishes building.

If that fixes your crash, we should tag it for f9-final.

That makes it a lot more stable in my limited testing.  I'd say we're good to tag.
