gnomesword2 must be missing a dependency in the RPM, this managed to get past YUM and YUMEX. $ gnomesword2 gnomesword2: error while loading shared libraries: libgtkembedmoz.so: cannot open shared object file: No such file or directory loading gtkembedmoz does not fix this problem.

This is caused by you having updated to later firefox version than gnomesword was compiled with. I've already built a new gnomesword to go with firefox-2.0.0.10, but its still waiting to be push to the stable updates, you can grab it at http://koji.fedoraproject.org/packages/gnomesword/2.3.1/2.fc8/i386/gnomesword-2.3.1-2.fc8.i386.rpm
