I did a standard export from my wordpress site (snbchf.com)
The XML file (2 MB) can be mailed on request.
Then I tried to import the file into my test site (another wordpress installation) which is in the snbchf.com/test/ directory.
It just imported 1 post, but duplicated the images of this post about 500 times, creating about 250 MB of duplicated images (!!), which then let my backWPup severely struggle.
Then I tested the same on a 3.3.2. installation, snbchf.com/TEST332, but the same behaviour.
Does this standard wordpress import really work ?
