Bug#947750: eom: Doesn't render Canon CR2 images

[Witold Baryluk <witold.baryluk@gmail.com>]

Package: eom
Version: 1.22.2-1
Severity: normal

eom does open Canon CR2 files, but they appear blank (transparant).

I made some images with Canon 5D Mk III, and the only thing that eom
shows is Size (5760x3840 pixels), and blank (tranparent) content.

In the view and in Image collection the image content is not displayed.

Clicking Details in the Properties pane doesn't show correct information
either, and shows the last correct image (usually some random JPEG) with
some random metadata from the last correct image, not currently opened file.

There are no errors or warning of any kind on the stdout or stderr during
open.

Interstingly after opening eom, and CR2 file, I see no dcraw or any other
similar raw libraries (libraw) loaded. Only jpeg, png, webp and few
others.

Maybe if the CR2 files are not supported, they should not be displayed in
the Image collection and accepted to be opened?

Best regards,
Witold
