Several indexed PNG images from the PNG test suite fail to load
GIMP: current master, 64-bit, self built on Windows under MSYS2.
OS: Windows 10 Home, 64-bit.
This is most likely related to the change that also caused issue #6501 (closed).
I'm using the http://www.schaik.com/pngsuite/pngsuite.html to test our image import plug-ins. Since some time, see the above-mentioned issue, several of the images from the PNG test suite are failing to load.
I'm using my own import test plug-in to test this (still a work in progress). Note that when using this you have to manually download the sample images and adjust paths for it to work.
Most if not all the failing images seem to have the following warning:
(file-png.exe:15692): GLib-WARNING **: 13:16:14.365: (../glib-2.66.1/glib/gerror.c:412):g_error_new_valist: runtime check failed: (domain != 0)
Below is the list of all images that failed loading:
