[Bug 912031] Re: ubiquity crashed with TypeError in partman_column_name(): argument of type 'NoneType' is not iterable

[John M. Rasor]

Same error - gagged trying to find a free partition. Details from sudo fdisk -l are below.
The installer offered only /dev/sde for "Alongside other OS". That's a usb external drive. OK, try "Something else". The crash occurred while scanning disk partitions. I'd wanted to put Precise on /dev/sda5.
