--- Comment #2 from Marco Albanese delian2@gmail.com 2011-12-09 02:35:24 PST --- I've the same bug when using ClutterFlow extension on banshee on my Radeon Mobility 7500 ( RV200, R100 chip).
It make the application crash when I hide the ClutterFlow interface, until then it works as expected.
Let me know if you need more information or I've to fill a new bug since the chip is differend (but IIRC the module is the same).
