Safari 3 on Leopard has a bug where it adds a Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryiSYJ0Lax1tMirv7S request header to a HTTP GET, following the re-direct after creating an issue. JIRA's multipart library can't handle this as it is not part of the HTTP spec, and it doesn't make sense to include this header in a HTTP GET.

As a result, users see the following error:
HTTP Status 404 - No view for result [error] exists for action [ViewIssue]

We may provide a patch for our multipart library if this starts to affect a lot of users, however it is ultimately a bug in Safari.
