A few days back Sebastain Bacher from the Desktop Team asked me if we had something that could take an ubuntu bug number as input and pull the bug title and description from Launchpad and push it to the Debian BTS. I tried hacking on it last weekend for hours together, but totally failed to get something working.
What I tried was to pull the data from Launchpad and then send it to reportbug via python’s subprocess, but was full of fail :p Later on, a friend confirmed that doing it this way could lead to failures because some weird stuff tends to happen (which did happen). So, now, I have all the required information from Launchpad, the best way would be to make something that works like reportbug with python. I don’t know to do it. I’ll be trying to get in touch with the reportbug maintainer and/or authors, in the meanwhile, if you’d like to help, you can branch from bzr. If I can something to work, perhaps, I can create a new project and push the branches there.
