Matthias: I don't think your problem is related to this bug report -- this one is about distinguishing what volume a particular directory resides on and returning the appropriate free space. Your one sounds more like faulty reporting of free space.
I've heard of a few other people having trouble with Sony phones, but don't have the hardware to debug it. If you would like to help me debug the problem, I suggest opening a new bug report. I've got a few commands you could run to collect data that would be useful in tracking down the problems.
