rgl normally works under Xvfb on Linux: we've been using that for the testing 'for ever'.
However R should not 'crash' on an error in a package, and the X11 device has error handlers set up by XSetErrorHandler(R_X11Err); XSetIOErrorHandler(R_X11IOErr); I don't see anything comparable in rgl. The error seems to be in the attributes, so I would have a closer look at those. In particular, how are you running Xvfb?: you may need something like Xvfb :5 -screen 0 1280x1024x24 & setenv DISPLAY :5 to ensure that you have a reasonable visual and hence colormap. (On my system the default is 12 bit.)
