nchar(with(list(2),ls())) gives an internal error. This is of course
a peculiar call (no names in the list), but the error is not caught
cleanly.
It is not clear from the documentation whether with(list(2)...) is
allowable; if it is not, it should presumably give an error. If it is, then
ls
shouldn't have problems with the resulting environment.

names in list)

Error in nchar(qq) : 'getEncChar' must be called on a CHARSXP # ls returned
a bad object
> qq
[1]Error: 'getEncChar' must be called on a CHARSXP
> qq[1]
[1]Error: 'getEncChar' must be called on a CHARSXP
> qq[2]
[1] NA
