linaro-android-media-create crashes when trying to partition a sd card

I thought this could be a dupe of bug 717129 so I suggested the reporter give the branch there a try but it didn't seem to help:

Are you 100% sure, on selecting [/dev/sdb] (y/n)? y

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

Can you try running l-a-m-c from lp:~salgado/linaro-image-tools/717129? It'd also be good to know on what system you're running so that we can try and reproduce it.

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.
