PNG Image not displaying for desktop icon on Fedora 16/17 with Gnome

view full story

http://unix.stackexchange.com – I attempted to create a desktop icon in Fedora Gnome but I only get a generic binary icon for my application. Installing Gimp or OpenOffice magically makes my icon appear. I used Google Chrome on Fedora as an reference for making a desktop icon using png images. Google Chrome uses 32-bit PNG files in /usr/share/icons/hicolor/#x#/apps/google-chrome.png, where #x# is the various resolutions: 16x16, 22x22, 24x24, 32x32, 48x48, 64x64, 128x128, and 256x256. The permissions on these files were all 0644 or -rw-r--r--. Google places their google-chrome.desktop file in /usr/local/share/applications/ w (HowTos)
