Comment 2 for bug 741230

I'm having the same problem. Looking to line 317 in ubi_prepare, I see that parted_devices is bring called. I have plenty of devices, some of which are indeed large enough to install (k)ubuntu on. But when I run parted_devices in the command line, I get nothing, just a newline. It's a shot in the dark, but my guess would be that the bug has something to do with that.
