gPhoto

I'm experiencing the exact same problem as described in
bug #825636: When capturing a image, the lens extends.
The camera then powers itself off. Transfering images
from the camera works fine.

Attached is the output of gphoto2 --debug --capture-image.

The syslog shows the following messages:
