The "Encoding" key is required in desktop entry files but is missing from the gnomemeeting desktop entry file. "Encoding=UTF-8" would be ok, and while at it, change "Terminal=0" to "Terminal=false"...
Oops, the buggy desktop entry is actually in redhat-menus. *** This bug has been marked as a duplicate of 105796 ***
