Changelog for 2.5.2 states that support for this model was added, so I suppose that whatever was used previously as a kind of "fallback" (I do not know what that was) worked, whereas the support for the specific model seems to be broken. I also notice that when using gphoto2 --list-cameras, this model is being listed twice:

Hi,

	thanks, that fixed my problem. In case other people have the same
issue, I used the quick and dirty fix of simply deleting the canon
driver from the driver directory:

mv /usr/lib/libgphoto2/2.5.2/canon** /tmp/

...this immediately had all the utilities working again.

Thanks again for your excellently helpful response, it's greatly
appreciated :)

Cheers
