GNOME Bugzilla – Bug 646203
Gray text on white background is hard to read (in the changelog area of the update viewer)

The changelog is displayed with gray text and white background, resulting low contrast between the text and the background, making it hard to read. Looks like an easyfix to me.
This used to be black, so it's probably related to the theme bits in gnome-3-0 -- I'll ask in gnome-design what the problem is.
I'm not spending much more developer time on gnome-packagekit, see gnome-software instead. If you can provide a patch I'll gladly merge it. Sorry.
