Regression: firefox bookmarks not imported anymore

We just find out that Firefox Bookmarks are not imported anymore.

We reproduced this bug with the 20120313 image which is based on ubuntu-defaults-it-0.1.5ubuntu2 (https://launchpad.net/~ubuntu-defaults-it-team/+archive/ubuntu-defaults-it/+build/3289547).

I tested the old image 20120311 based on ubuntu-defaults-it-0.1.4 (https://launchpad.net/~ubuntu-defaults-it-team/+archive/ubuntu-defaults-it/+build/3277318) and it's not affected.

I also tryied to build again today an image with the 0.1.4 package and it's still affected, so it's doesn't seems related to the package content.

I compared the /usr/lib/firefox-addons/distribution/ content and the only difference is that in the working CD there's also an distribution.ini.ubuntu-defaults file.

I'm keeping both working and not working images, let me know if you want more files from them.

Thanks in advance
