I tried debugging this. Under the debugger it seemed to run successfully! Itt showed a list of package names to select from in the prompt area (which it didn't do before), and, I think, let me select one of them.
During the package selection logic, It searched unsuccessfully for a DESCRIPTION file in the working directory and its parents (the package had been loaded from a library, and the source code was one level below the working directory).
I did notice the wrong type argument message several times while I was tracing through the functions.
I also noticed some uses of file-exists-p; I have a hazy recollection this function accounted for some similar errors because it wasn't defined, or was defined differently, in earlier versions of emacs. But 24.4 is pretty current.

To: ess-help using r-project.orgess)Top > Developing with ESS > ESS developer ronment, when I do C-c-C-t C-s or the equivalent command (see subject) the echo area shows "wrong type argument: stringp, nil".
After toggling on the emacs debugger:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
call-interactively(ess-r-set-evaluation-env record nil)
call-interactively(execute-extended-command nil nil)
Also, the info documentation seems internally inconsistent; the news indicates using the command above is the way to go, but (ess)Top > Developing with ESS > ESS developer, section 10.3, seems to have the old commands, which do not work--or at least C-c C-t C-a gets me the same error.
