1) boot Ubuntu from a live-USB stick on a Fujitsu Q550
2) directly after the desktop appeared the bug message appers
3) despite the live-USB stick there is also a SD-card in the SD slot, this card can not be mounted
4) the daily build 20130131 32 bit version of Ubuntu 13.04 is used
5) terminal output about dconf
