While having no problems with the new Ubuntu 13.04 Friends app it suddenly stopped showing my Twitter feeds. It began when I started Twitter in Firefox and Ubuntu wanted to activate the Twitter webapp. It created a new Twitter online account (using my username instead of e-mail adress) alongside the one I already had (which used my e-mail adress). I removed the original one since it seemed the new account connected to Friends, which it didn't. I then created a new online account based on my e-mail adress, but to no avail. No tweets show up anymore. Several "internal problems" popped up while I tried to figure out what was wrong.
