Actually, today I fixed the problem in Spacewalk nightly in the following
commit:

https://github.com/spacewalkproject/spacewalk/commit/22904881c43599d73fb4181a0885000cb49f50bc

To fix this issue on an installed Spacewalk 2.1, please apply the same change
to the following file on your Spacewalk:

/var/lib/tomcat[56]/webapps/rhn/WEB-INF/struts-config.xml

and restart tomcat.

Thank you for the report & sorry for the trouble.
