I just recently noticed that all the theme thumbnails (with the exception of "Simple" and "Crux") all have missing thumbnails -- that is, the logo with a "?". I don't recall if it has always been like that. Any insight?
(gnome-theme-manager:5531): capplet-common-WARNING **: Received EOF while reading thumbnail for gtk: 'Glider', metacity 'Glider', icon: 'gnome', font: 'Sans 10'
Obviously bugs out while reading the custom theme. Thumbnails appear correctly when using any other theme.
Update: occurs whenever 'Glider' gtk theme is being used. Anybody else seeing this behavior?
