In the Create Partition window, I choose from the Type menu, "Custom (enter filesystem type)". But in the Filesystem field, I have been unable to guess any entry-text that works!

I am not running Ubuntu or using gnome, but I understand that Ubuntu has a package 'hfsplus'
that provides the mkfs.hfsplus utility. You can always run it directly from the command line.
