totem crashes when launched from mythtv

I've added a button in my mythtv menu to launch totem connected to an online radio station I like by adding the following to the library.xml file:

    <button>
 <type>MUSIC_PLAY</type>
 <text>Hober</text>
 <action>EXEC /usr/bin/totem --fullscreen http://play.hober.com/hober.mp3</action>
    </button>

I've already tested the EXEC portion of the above statement from a command line and it does exactly what I want- connects to the online radio station with a fullscreen visualization. However when I try to click on the button that I created in the Mythtv menu, Totem starts and I get about half a second of visualization and then everything hangs and I have to kill the program to get out of it.

I tried running mythfrontend from a command line to capture any error messages and got this:

<normal mythtv startup messages,followed by:>

My guess from reading this is that Totem is trying to grab the sound server but mythtv has control and isn't letting go? (I'm assuming the resume success part is after I did a force quite on the totem screen) I'm using Ubuntu 10.10 and all mythtv packages have been installed from the Ubuntu software center so it's all standard.

Any suggestions for how I can get this to run? Suggestions for alternative methods to get a radio station to play through mythtv without too much hackish type code are also welcome.

Thanks.
