[R-SIG-Mac] R stops abruptly applying textures in rgl

[Agustin Diez Castillo]

Duncan,
Find the script [1] , SessionInfo [2]  and the Mac error [3]  in case it helps. Executing R from the terminal R doesn't
freeze and I got the same message that in Ubuntu 13.04 [4] 
# With rgl installed in ~/Library/R/
library(rgl)
# Set directory
setwd("~/")
#Working
rgl.bg(sphere=TRUE, texture=system.file("textures/bump_dust.png", package="rgl"),back="filled")
#Copying the same texture to the working directory
system("cp ~/Library/R/3.0/library/rgl/textures/bump_dust.png bump_dust.png")
# expanded version also works
expanded<-paste(getwd(),"/bump_dust.png",sep="")
# Testing
rgl.bg(sphere=TRUE, texture=expanded,back="filled")
#Hanging R.app
rgl.bg(sphere=TRUE, texture="~/bump_dust.png",back="filled")

three different machines, all running 9.2. The same in Unbuntu 13.04 drops a warning message [3] but R continues running.
