trac-xmlrpc problem

Hello there.

I’m now trying to use eclipse with mylyn + trac.

I installed trac-0.10.4 from:
Index of /repositories/devel:/tools:/scm/openSUSE_11.0
It works fine.

because it doesn’t have the xmlrpc plug-in for trac, I manually installed it by compiling a source from trac’s plug-in site, XmlRpcPlugin - Trac Hacks - Plugins Macros etc. - Trac

python bdist_egg

cp dist/*.egg /srv/trac/env/plugins

But there seems to be a problem.
On eclipse, I cannot access my trac-task repo by XML-RPC, it gives me HTTP Error 500.
Only Web, Access Type, is fine.

How can I solve this problem?
