Comment 1 for bug 452347

Note that the API documentation of the request method explicitely requires str objects, not unicode (http://www.moovida.com/documentation/api/elisa.plugins.http_client.http_client.ElisaHttpClient-class.html#request).

Note that there was also a failing unit test for the HTTP client that had been commented out until someone would take the time to understand the issue, which you did.

I'm not sure this should be considered as a bug, the documentation being clear about the expected value types.
