This has a documented workaround:
  Click on Edit -> Preferences
Then, for each mail account that you have (I have 3), click on it, and
select:
  Edit -> Defaults tab
and change the Sent Messages Folder to the Sent folder instead of the
incorrect #Sent folder.

I do not know why a fix has not been pushed out for this, 6 months after
the bug showed up.  It affects a huge number of people.
