Cannot read serial from /sys/bus/usb/devices/

After an update to qemu 1.6 I can't start any of my images. Qemu always crashs. I tried it with root and as a normal user... Here are some log entries I get:

That log does not look very helpful. Could you please provide more details like command line options and the exact output of QEMU if your problem still persists with the latest version of QEMU? Thanks!
