Not sure what `xvfb-run on Linux' is, as it is not on my Linux (FC3). If you Google it you will find a number of problems reported on Debian lists. Here I would suspect timing.

What I do is to run Xvfb on screen 5 by

Xvfb :5 &
setenv DISPLAY :5

and do not have a problem with the jpeg() or png() devices. I do have a problem with the rgl() package, but then I often do on-screen (on both 32- and even more so 64-bit FC3).

You really should update your R.
