Bug reported by Javier Kohen in the Debian BTS 2 weeks ago. Occurs with Xserver 1.3. He says:

X crashes with the following error message when Google Earth loads (I'm not certain exactly when this happens, I think as soon as the first 3D view is about to appear):
(**) RADEON(0): RADEONSaveScreen(2)
ProcXCloseDevice to close or not ?
SynapticsCtrl called.
SynapticsCtrl called.
(EE) DoSwapInterval: cx = 0x8490470, GLX screen = 0x8265638"

Later, he caught a backtrace with debugging:
