SOAP4R seems to conflict with actionwebservice

I am getting the following error when any test fails “uninitialized
constant SOAP::SOAPNamespaceTag” If any exception is raised it raised
this exception instead.

Very strange. I have googled around a bit and some people have
suggested some workarounds for the older versions of SOAP4R or rails
but none of them work with the 1.5 version of SOAP4R and 2.1 version
of rails.

Does anybody have a solution to this problem?
