I installed a new GTK theme for both GTK 2.0 and 3.0, and now there are certain windows that have unreadable text in Nautilus. The text color is black on a light background, I made sure of this with the color manager in Gnome Tweak. For example, I can't see anything in the file properties dialog, or in the popups that occur when doing file operations, etc. If I highlight the invisible text it shows up. This also happens in Gnome Mplayer, I can't see any text when trying to change my preferences, so I know it isn't an issue with Nautilus. I can see my files and the text in the pane of nautilus just fine. If I switch to one of the themes that was installed by default, everything works fine.
I'm using Crunchbang with the Fleche GTK+ theme https://github.com/hdni/Fleche
