The following work-around helped me on this. In order to make it work you need to have Xnest installed on your computer. It comes standard with most Linux distros so you should be good to go.

While in Xgl open a terminal and type the following:

Xnest -ac :1 & export DISPLAY=:1

Press ENTER. That should open up an Xnest window. Go back to your terminal and type the folllowing:

limewire &

Press ENTER. That should do it.

I wish I were more tech savvy and could tell you exactly why that works, but I cannot. I just know that it works for me.
