[R-SIG-Mac] rgl crashes after one successful draw on R.app

NOTE: problem is with R.app, looks OK on command line R

This is really odd, and probably 100% local to me, but I'm at a loss as to a next step.

After narrowing things down, here's how to reproduce:

showSomething <- function() {
showSomething() # works as expected.
# Close the current rgl window
showSomething() # crashes R with the following report:

*** caught segfault ***
address 0x0, cause 'unknown'

1: .C(rgl_dev_open, success = FALSE)
2: rgl.open()
3: open3d()
4: showSomething()

This will probably work fine for any of you, it's so simple and fundamental.  If I don't close the open rgl windows, it doesn't crash, and I can execute the function over and over successfully.  And the same thing happens if I just do the commands inside the function individually.  SessionInfo() below.

Perhaps something is corrupt with my X11 window system?  Thanks, Bryan
