slideshow screensaver exit messes up menus

I'm having a problem & can't figure if its the addon or certain skins. Sometimes, when the screensaver exits I end up in a situation where the menu system becomes totally unresponsive. I can hear the audio pop/click when I press the arrow keys or OK on my remote but the menus do not respond.

This is happening under Frodo RC2 running on Ubuntu and has happened with the Quartz skin & Hybrid.

I've checked the log and I don't see anything.

Any thoughts?
