Bug 332741 – media-gfx/gthumb can't view Nikon RAW NEF files

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Fabiano Francesconi 2010-08-14 14:41:34 UTC]

I have this strange issue. I can't view any NEF files using gthumb (both stable and keyworded version).

The current set of useflag is: cdr exif gnome-keyring gstreamer raw tiff

The stable version will show the image as a small "stamp". Those are 12mpx images and are displayed so badly.
The keyworded version seems to be a little bit better but the images cannot be seen at all.

I don't know if it's something related to the app itself or something bad with my system but I can't find anything on the Internet.

Will you help me, please?

Is gthumb supposed to support NEF files at all, I have never heard of it so a sample file could be useful (attached to this bug).

[Comment 2 Fabiano Francesconi 2010-08-15 22:58:40 UTC]

From few bugs report I read (on ubuntu scene) it seems that it should read NEF files.

Here's the thing:

Nautilus shows me the miniature next to the file but I can't use evince (document viewer) to view those photos since it doesn't support them.

GThumb loads correctly the thumbnails in the bottom navbar but it can't show the photo once I try to load by clicking on the thumbnail. Using any JPEG image it works.

Here is the picture:

ok this is the raw file format of Nikon cameras, it seems to embed jpeg and tiff for preview purpose. It works just fine here, what is the output of emerge -pv gthumb tiff ?
Also, do you have:
/usr/lib64/gthumb/extensions/libraw_files.so

and is the "Raw format support" extension enabled in gthumb extension menu ?

emerge --info

I can confirm this, and add a new twist...  when I try to open Fabiano's .NEF, I get the same result: a blank pane in gthumb.  When I try to open .NEF files from my wife's Nikon D60, they come out with the colors distorted beyond recognition, as in this screenshot:

Output from emerge -pv gthumb tiff:

Let me know if there's anything I can do to help test further!

Image is opened fine with 2.12.0, please try with it or 2.12.1

[Comment 7 Fabiano Francesconi 2010-12-18 23:49:34 UTC]

Using gthumb-2.12.1(cdr exif gnome-keyring gstreamer raw tiff -debug -http -slideshow -test) I can't see the picture (I haven't tried with 2.12.0)

I'll attach some screenshots.

I have tried with your same USE flags and your posted image:
http://dl.dropbox.com/u/355313/gthumb/DSC_0021.NEF

and it still works fine for me.

Do you get the same problem on a new created user account? Do you get any error message when running gthumb and opening affected image from a terminal?

[Comment 11 Sergiy Borodych 2011-01-06 13:20:17 UTC]

similar problem
thumbail view ok, but image not - just empty screen

[ebuild   R   ] media-gfx/gthumb-2.12.1  USE="exif gstreamer raw tiff -cdr -debug -gnome-keyring -http -slideshow -test" 0 kB

also detect some output like
$ gthumb
(gthumb:16365): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed

Sorry, I am not able to try it since I have removed Gentoo from my notebook :p

I guess #11 will still be able to see that.
