Comment 3 for bug 902227

I saw the same issue once on my debian system, and I think it is related to the udev functioning. The reason is that there are nodes for partitions in /dev but no real partitions on SD. I haven't yet figured out why this happens, but there is a workaround.
Try to remove dev nodes for partitions except the device, for example if you have SD card is /dev/sdb, than remove all files like /dev/sdbX, where X=1,2,3,... and then rerun l-i-t.
