This will be fixed in the next few hours. After talking to pitti on #ubuntu-desktop, he uploaded a new package (no change upload) so that the template (and upstream translations) is imported.
pitti tells me that this was because: "the same version is both superseded and published in lucid, which means that its component was moved and I just happen to know that it moved from universe to main" -> https://edge.launchpad.net/ubuntu/+source/gwibber/+changelog
Note that there will still be some untranslatable strings until bug 520462 is fixed upstream and the changes integrated in the package.
