ok, this problem is very fishy. In short libgphoto2 misdetect the camera because it has the same ID as a much older model. try to force using --camera "Canon PowerShot A520 (PTP mode)"
it should work this way -- [feisty] Can no longer import photos from my Canon PowerShot A520 https://launchpad.net/bugs/85390 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
