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

[Agustin Angel Diez Castillo]

Hi,
When applying textures to an rgl object I can do it without problem if the applied texture if the texture file is called in an expand form [1]. However if the same file is called with tilde [2], R will stop abruptly. I've tested it in three different machines, all running 9.2. The same in Unbuntu 13.04 drops a warning message [3] but R continues running.
