Comment 5 for bug 583342

Guys and gals I had the exact same problem but managed to resolve it quite straightforwardly by going to CompizConfig Settings Manager, scrolling down to the Utility section, selecting 'Workarounds' (if not already selected), click on the workarounds icon, and you will then see a new window with a tab called General and the first entry is "Legacy Fullscreen Support" which is probably unchecked.

Just check it to on and you should find the Geeqie goes fullscreen without any panel intrusions.

It worked for me.

Best of luck. Please do check back and let the bug report know if this fixes it.
