I guess it's not a Tramp error. Interesting lines from your backtrace:

- `file-attributes' is called with one parameter.

- The corresponding Tramp file name handler is called with 2
  parameters. See `file-attributes' implementation in dired.c

- Tramp calls `ange-ftp-file-attributes' with the same 2
  parameters. Unfortunately, `ange-ftp-file-attributes' has not
  implemented yet the second (optional) parameter.

Best regards, Michael.

For backward compatibility with old file handlers, I think that dired.c
should be careful to call the `file-attributes' handler with two args only
in the case where the second arg is non-nil.

Good point.  I will fix that.
