Oh, this may be the same issue as #813 (string exception raised to web renderer?). It occurred at about the same time for the same user. I suspect this is the cli version of this bug and #813 is the wui version of this bug.

Oops, yes, the TahoeError class in source:src/allmydata/scripts/tahoe_cp.py#L19 must either set self.args or override *str* (and maybe *repr*). The error occurs when some other code attempts to str-ify one of these exceptions.

This is a CLI-side error-reporting bug. There must be a separate (but similiarly-shaped) bug in the webapi or wui code for #813.

This must have been fixed at some point. For tahoe cp --recursive --verbose, I now get a usage message and

/path/to/bin/tahoe:  cp requires at least two arguments

Oh, I may have misinterpreted the ticket description; "tahoe cp --recursive --verbose" must not have been the complete command.

Nevertheless I believe this would have been fixed as a side-effect of changeset:80252debcd94fc28 and changeset:731e3d68dff0f8c9. Notice in http://tahoe-lafs.org/trac/tahoe-lafs/changeset/4435/trunk/src/allmydata/scripts/common.py that TahoeError calls the superclass Exception.*init*, which will set .args. Its subclasses [HTTPError]source:src/allmydata/scripts/common_http.py@4435#L84 and [MissingSourceError]source:src/allmydata/scripts/tahoe_cp.py@4435#L30 also call TahoeError.*init*.
