Nope, already tried it.

In fact at first the directory was there, and I successfully (I think) done the second part of the How-to. But then I realized that not everything was installed (I had only the Contacts icon, not the others in the first post). Therefore I installed the missing apps, and got an error when launching them, so I tried to do the second part of the procedure again, and somehow screwed up somewhere... No I have no akonadi directory in /home/user/.local/share nor in /home/user/MyDocs. It sucks. Well, I suck. I screwed up.
