[R-sig-Debian] [R] fix and edit don't work: unable to open X Input

[Paul Gilbert]

(moved from R-help)

I tried this on Ubuntu with R-2.14.1 built from source, and I do not get 
the segfault problem. (I don't at the moment have a debian binary R, or 
I would confirm whether I get the segfault problem.) My sessioninfo() is 
reporting additional information about namespace imports:
