Hello Anne,

I can't see any relevant to that problem in the changelog of libgphoto2
2.4.6, which you can find in unstable, but you may want to try that
version anyway?

Oh, maybe that one?
| libgphoto2:
|    * Fixed a problem during file retrieval which causes Canon Normal
|      --capture-image-and-download errors, handle CR2 and CRW mimetypes.

What if you try 2.4.1-3, which is available in stable? That might help
narrowing down the range of commits which might have introduced your
bug.

I'm getting in touch with upstream authors. ;)

Mraw,
