1. In iESS shell, when I input ?Ops, the emacs will crash, no response.
2. In ESS

    library(xts)   # sent to R
    as.Date       # will pop up the auto complete list

but then the auto complete will crash, with no response,
this may caused by as.Date is define in two packages: zoo and base

emacs version 24.2.1
ess version 12.09 rev.5167
R version 2.15.1
