Description

Created attachment 330927 Windows icon file that shows up corrupted in nautilus and eye of gnome

Some windows icons display as garbage. An example is attached. It is supposed to show a green circle - open it up in GIMP to see how it is actually meant to look like.

The .ico file contains the following sizes:

16x16 1bpp, 1bit-alpha, 2 color palette, uncompressed 32x32 8bpp, 1bit-alpha, 256 color palette, uncompressed 128x128 32bit, 8bit-alpha, no palette, compressed (PNG)

Some of the settings must be throwing nautilus off. Eye of Gnome/EOG has the same problem.
