I was able to recreate this on wily.

The problem is the leading slash in the PPA name and there are surprising number occurrences of this at errors.ubuntu.com.

https://errors.ubuntu.com/bucket/?id=/usr/bin/add-apt-repository%3AIndexError%3A/usr/bin/add-apt-repository%40119%3Ashortcut_handler%3Ashortcut_handler%3A__init__%3Amangle_ppa_shortcut

The instructions for adding a PPA on Launchpad don't display a leading slash but it still seems worth fixing.

[Launchpad Janitor (janitor)]

This bug was fixed in the package software-properties - 0.96.13

---------------
software-properties (0.96.13) wily; urgency=medium

  * Properly parse a ppa which has a leading slash, something which a lot of
    people seem use as an argument to add-apt-repository. (LP: #1426933)
