I get the following error when trying to fetch a post from a serendipity v1.0 blog.

/usr/local/lib/ruby/1.8/xmlrpc/client.rb:552:in `do_rpc': Wrong content-type: (RuntimeError) <?xml version="1.0" encoding="UTF-8"?> <methodResponse> [lots of xml snipped ...] </methodResponse> from /usr/local/lib/ruby/1.8/xmlrpc/client.rb:420:in `call2' from /usr/local/lib/ruby/1.8/xmlrpc/client.rb:410:in `call' from /Users/stephen/Applications/TextMate.app/Contents/SharedSupport/Bundles/Blogging.tmbundle/Support/lib/metaweblog.rb:31:in `getRecentPosts' from /Users/stephen/Applications/TextMate.app/Contents/SharedSupport/Bundles/Blogging.tmbundle/Support/lib/blogging.rb:542:in `fetch' from /Users/stephen/Applications/TextMate.app/Contents/SharedSupport/Support/lib/progress.rb:11:in `call_with_progress' from /Users/stephen/Applications/TextMate.app/Contents/SharedSupport/Bundles/Blogging.tmbundle/Support/lib/blogging.rb:541:in `fetch' from /tmp/temp_textmate.v2ZuUO:3

I'm using cutting edge textmate 1112.

I can connect to the serendipity blog using ecto using the metaWeblog api. Here's the endpoint I am specifying in Setup Blogs:

Thanks for any pointers.
