I just sent an email from mediawiki.org and noticed that the subject line appeared twice in the email header. I tried it on my local wiki, running MW 1.19 (r110988 to be precise) and it happens there too, so it seems like a MediaWiki code issue, not specific to the mediawiki.org setup.
Here is the full email for reference:

Hi Ryan,
could you create a labs account for me, so I can use Gerrit and play around with git? (I need a labs account for this according to http://www.mediawiki.org/wiki/Talk:Git/Workflow#Users_already_created.3F ). My preferred wiki-username is "tbleher". I already have an SVN account with extensions access, which is also named "tbleher". My preferred email address is ThomasBleher@gmx.de.
Thanks a lot!
Thomas Bleher
