Rails 1.2.1 breaks web service: "Unknown charset: u"

Rails
1

Hello, I have a web app with a web service (Actionwebservice) component
that was working fine under Rails 1.1.6. I upgraded to 1.2.1 and the
regular http controllers work fine but when I try and call a web
service, I get this:

XSD::Charset::UnknownCharsetError in ServerController#invoke_submit

Unknown charset: u

Note that I did not re-run the “rails” command after upgrading, maybe I
should have?

Here is my soap request envelope:

<?xml version="1.0" encoding="utf-8" ?>

<env:Envelope xmlns:xsd=“http://www.w3.org/2001/XMLSchema”
xmlns:env=“http://schemas.xmlsoap.org/soap/envelope/”
xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”>
env:Body
<n1:GetSessionId xmlns:n1=“urn:ActionWebService”
env:encodingStyle=“http://schemas.xmlsoap.org/soap/encoding/”>
</n1:GetSessionId>
</env:Body>
</env:Envelope>

Any ideas?
Thanks
