If you write some latex, click 'LatexIt!', then save the message before closing the run report, the report becomes part of the draft and is not recognised when you reopen the message.
Also, though the text in the report can then be removed, the pretty background image cannot seem to be removed with the standard Thunderbird message editor. I was also unable to find a HTML editor for the current version of Thunderbird in the Ubuntu repositories (such an editor could probably remove the offending image).
