I agree to Robies summary that this should be filed and discussed with Debian first to avoid getting a Delta for this.
Chaskiel, could I ask you to be so kind and open/discuss that with Debian.
Especially since you own the system where this happened first.
Thanks in advance if you do so, and let us know of the Debian bug numer.
We can link that here and get tracking as soon as it is resolved with Debian to consider pulling it into Ubuntu as well.
