Aha I see that you tried it in virtualbox. So, your system is not corrupted.
You know virtualbox is not so stable than kvm(but faster in my feeling), which makes trouble to the latest development versions.
Please use for your test the latest virtualbox(4.1.18 AFAIK) that you can find in the ppa of Felix Greyer:
