I am seeing this too when running stellarium, on Feisty with ATI Radeon 9200SE (RV280) graphics card with the free "radeon" driver, with dri enabled. Managed to get round this by downgrading libgl1-mesa-glx & ibgl1-mesa-dri from 6.5.2-3ubuntu7 to 6.5.1~20060817-0ubuntu4. Tried 6.5.2-3ubuntu6 & 6.5.2-3ubuntu1 but problem remained.
