[R-SIG-Mac] Lion and X11

[Martin Renner]

Thank you to everybody who replied! Simon, on my machine, I can reproduce this segfault every time using these steps:

- open Terminal.app (or iTerm or Aquamacs), start R --vanilla  (RStudio, or R.app)
in R:   
   - x11()   (in Terminal, my R defaults to x11, without me doing anything; in R.app or RStudio, I call x11() to reproduce this segfault. 
   - plot (1:10) or any other plotting command. 
I am not aware of any other conscious or subconscious steps I'm taking. Plotting to quartz() or pdf() works fine. My .bashrc sets R_LIBS and the usual additions to the default PATH, nothing that should affect R or x11. Since I haven't heard back a flood of people saying, 'yes, me too', I suspect, this issue is specific to my setup. I've tried clearing out any preference files related to x11, to no affect. When calling plot (1:10), I get a new x11 graphics window, ten circles and an x-axis with tick-marks, and a segfault. No box(), no y-axis. There's no .Rprofile in my home directory. Are there any other preference files that could be corrupted? 

My display variable looks fine, so Christian seems to have a different issue than me.
