l10n_install cannot be installed via Aegir

I just tried installing l10n_install via Aegir, but am getting an integrity constraint violation for a duplicate 'l10n_install' in the system table. I don't really know why l10n_install could be the cause of that, but installing any other profile works for me.
So I am basically just opening this to see if anyone can reproduce it. It might very well be something on my end, but again, every other profile works...
