Typo correction:

1. emerge =x11-libs/gdk-pixbuf-2.36.9

[Comment 2 Gilles Dartiguelongue (RETIRED) 2017-09-03 13:22:55 UTC]

There seem to have been changes in tiff loading between 2.36.6 and 2.36.7. Could you please report this issue upstream and attach a sample tiff file if possible ?

Patch to restore tiff loading

I had a look upstream but I cannot see how to file a bug report in there. 
Anyway, Viewnior fails to load *any* tiff image. Can you please report this upstream? I can supply a typical tiff image here.

The attached patch for io-tiff.c (which I derived by diffing the working 2.36.6 and the failing 2.3.9) restores proper functionality.

Also please note tha the patch I uploaded in my previous comment does not solve the problem.  Plese delete it

Probably this bug:
https://bugzilla.gnome.org/show_bug.cgi?id=786342

gdk-pixbuf-2.36.10 was released 2 days ago.
Fix (https://git.gnome.org/browse/gdk-pixbuf/commit/?id=66537d1ecf7e857a0a443c1ebf72baf6f19dd3e4) for above bug was committed after this release, so please backport it.

[Comment 6 Andreas Proteus 2017-09-14 11:36:13 UTC]

I applied the patch from upstream but this did not fix the problem.
Please note that now there is no working version of gdk-pixbuf in portage. Last version (gdk-pixbuf-2.36.6) that could load tiff files  has been removed.

Have you added GNOME2_EAUTORECONF="yes" at the top of ebuild (before 'inherit ... gnome2')?

Please either backport the fix to either gdk-pixbuf-2.36.9 or stabilize 2.36.10 instead.
