I'm using gnome on fedora core 6. My panel is set to transparency. The icons show up with a gray background. I checked the PNG files and they have the transparency set to 230,230,230. I then added an add_alpha call to the pixbuf to see if that would help, all to no avail.
Does anyone else have this issue? I don't know python at all and linux GUI even less so any help would be appreciated.
