I wanted to import a portfolio into an existing account. I got the following warning messages trying it on 1.10 dev. The import was from a 1.6 Mahara site. I can provide the file (for my own reference, it's kristina_knox_portfolio_20130124.zip). The import succeeded and I had the pages but maybe some things didn't work alright. I did not import any files or the journal. I just imported the pages.

As it is a small bug, I set its milestone to 1.10
