Comment 11 for bug 173294

Right, there's any icon, but my first comment still applies. For such a little change in the .desktop file it would be enough to just modify it (without adding a patch system, which isn't recommended if there isn't already one), and I think dh_install (or cp in debian/rules) is enough to install the icon and .desktop file.

Don't give it much importance though, those are just my five cent. I'm not a MOTU (yet) and perhaps you'll find a sponsors who likes it like it's now ;).
