After having installed the udisks package from the PPA both my external optical drive and my mobile phone with USB mass storage get mounted automatically.
Couldn't test my internal optical drive now, because I have moved it to another machine for the time being.
If the other people affected could please test the proposed udisks patch and comfirm that it helps we could mark this report here as a duplicate of https://bugs.launchpad.net/bugs/539515
It appears to me that the patch in https:/ /bugs.launchpad .net/ubuntu/ +source/ udisks/ +bug/539515/ comments/ 109
fixes also this problem.
