Description of problem:
I'm getting "500 Internal Server Error" when trying to use packages.removePackage(key, packageid).


Version-Release number of selected component (if applicable):



How reproducible:
always


Steps to Reproduce:
1. I have custom channel with 4 packages (same name, incremental version)
   (pid=3893..3896) and 4 erratas (each errata contains one of the packages)
2. Use API to delete the packages from channel
   >>> import xmlrpclib
   >>> client = xmlrpclib.Server('https://ibm-ls41-02.rhts.eng.bos.redhat.com/rpc/api', verbose=0)
   >>> key = client.auth.login('admin', 'admin')
   >>> client.packages.removePackage(key, 3893)


Actual results:
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.4/xmlrpclib.py", line 1096, in __call__
    return self.__send(self.__name, args)
  File "/usr/lib/python2.4/xmlrpclib.py", line 1383, in __request
    verbose=self.__verbose
  File "/usr/lib/python2.4/xmlrpclib.py", line 1137, in request
    headers
xmlrpclib.ProtocolError: <ProtocolError for ibm-ls41-02.rhts.eng.bos.redhat.com/rpc/api: 500 Internal Server Error>


Expected results:
Should work (I'm able to remove the package from WebUI)
