/usr/share/pixmaps/chess.png is world writable apparently due to bad umask
setting in the FE build system; its maintainers have been notified.
FE5 and devel are affected and this should be fixed in the package anyway, a fix
is to use "install -pm 644" instead of cp to install the file. In the FE4
package the file is 664, not world writable, but I'd recommend fixing this in it
Fixed (FC-4, FC-5, devel) and built (FC-5, devel), will be in the next push.
