Twice whilst drafting <http://n2.nabble.com/-tp3636586p3647403.html> an attempt to attach a second image resulted in an error:

upload failed - the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is null

and the first attachment was removed from the draft.

The errors occurred after I clicked the Insert image button and AFAIR the error dialogue (screen shot below) overlaid the upload dialogue.
