Comment 5 for bug 253039

finally it worked changing the name.
btw: this is the description of the name field at my https://launchpad.net/~USER/+edit site: "A short unique name, beginning with a lower-case letter or number, and containing only letters, numbers, dots, hyphens, or plus signs."
that should be rewritten until the bug is fixed.
