If you read this on planetapache.org, the post title most probably says “Bertrand”.
This is due to the move of my blog to wordpress.com hosting: seems like, the planetapache software incorrectly takes the last <title> element of the feed item as the post title, even if it is a media:title as is the case in my feed.
Now I understand why all of Dims’ posts there are titled Davanum there, and all of Nick Kew’s posts niq ;-)
bertrand's brain grep 
looks like we need to fix planetapache :)
Seems like tt’s been fixed in the meantime, http://planetapache.org/ now shows the titles of my post correctly. Thanks Ted and Thom!
