Arduino Icon not showing up on Fedora 15 Task Bar

First post and first "thank you" to anybody who helped make the Arduino world. It is truly wonderful.

I run Arduino on Linux (Fedora 15) and everything is fine, except that when I go to place my most used applications on the task bar (FileZilla, Firefox, Bluefish, etc. and of course Arduino) the Arduino logo/icon does not show up. It shows up in the dialogue where I get to select the apps for the task bar, but not when it is on the task bar itself. All it shows is the red circle with a slash through it. It's functional -- just not very attractive!

Just wondering if anyone had any ideas? The Linux spin I'm using is the LXDE one.

Thanks.
