The issue appears to be that when WebKit sent a multipart/form-data boundary with a "+" character in it, the server-side software wouldn't decode the request properly. (When there was no "+" character in the form boundary, everything worked fine.)
Mark didn't say what software he was using on the server side to decode the HTML form data, but it probably requires a simple update to fix the issue.
