R help - Sep 2011 - dump.frames, debugger and the "..." argument

Dear List, 

i run R non interactively and use option(error = dump.frames) to reconstruct the
cause of errors for debugging. One of the functions in the call stack however
uses the "..." (dot dot dot) argument. When I run debugger() and try
to browse to this functions' environment I get the following error message:

Error in get(.obj, envir = dump[[.selection]]) : 
  argument "..." is missing, with no default


Some googleing showed that this seems to be a more common problem but I was not
able to find any solution.

Any ideas?

Well, we're just over a month from a new release.  Post a reproducible 
example and this will likely get fixed.

Well, its 2.10, a slightly old version. I know that I am advised to upgrade to
the current version. Unfortunately the installed version on the machine I am
using is out of my reach. The reproducible example would be:

dummyFunct = function(a, ...) {
  b = 2* a
  c = d           # should cause error
  return(b)
}

options(error = quote(dump.frames(dumpto = "last.dump", to.file =
TRUE)))

dummyFunct(1)
load("last.dump.rda")
debugger(last.dump)
# selection of call 1 causes:

# Error in get(.obj, envir = dump[[.selection]]) : 
#  argument "..." is missing, with no default




R version 2.10.1 (2009-12-14)

Looks like Brian was right, it has been fixed.
