Compiz using excessive CPU when empathy connected and contact list window open

[Michael Hart]

When sad idle with nothing more than empathy and a terminal open, compiz is using between 10-25% CPU and X using 10-15%, as I'm on a laptop this makes for a somewhat warm lap and short battery life.

If I quit empathy, CPU and heat drop back down to a minimum. If empathy is visible but offline then the cpu usage also drops to a minimum. If empathy is Available but the main window (contact list) is not showing then the CPU usage is also normal so this appears to be purely related to empathy's contact list. My apologies if this is filed against the wrong application.
