Autofocus fails after using it once. Requires reconnection of camera to use again.

Using a Canon EOS 60D because the Canon EOS 40D will not autofocus in live view at all (the 40D also does not support gphoto2's eosremotecapture).
With Entangle, opening up live view and pressing 'a' for autofocus works. Once. But once you attempt to auto focus a second time, it simply refuses to do so. Even if you close Entange and reopen the program. You have to reconnect the camera from USB and reconnect it.
Fine and coarse manual autofocus still work however.
This is with AF mode enabled on the camera lens, in 'M' manual mode (as opposed to macro or bulb, etc). I tried both quick autofocus and live mode autofocus and both produce the same results.
Looking through other bug reports, there seems to be a bug in the autofocus code somewhere because the gphoto2 library is happy as can be to autofocus over and over without reconnecting.
Also, just FYI for anybody else with this question. The EOS 50D supports autofocus during liveview but only with the button on the body but not the remote. The 60D supports autofocus with either. That's how it functions with the official EOS Utility software anyway.
