Bug 445515

Description of problem:
When there is server set like this in the /etc/sysconfig/rhn/up2date:

serverURL=http://www.yahoo.com;https://xmlrpc.rhn.webqa.redhat.com/XMLRPC;

I can not register. When I register with correct server in the config and then 
set it like this ^, `yum install ...` and so works.


Version-Release number of selected component (if applicable):
rhn-setup-0.4.17-8.el5.noarch
yum-3.2.8-9.el5.noarch
yum-rhn-plugin-0.5.3-6.el5.noarch


How reproducible:
always


Steps to Reproduce:
1. change /etc/sysconfig/rhn/up2date to contain serverURL like that ^
2. # rhn_register


Actual results:
