I uploaded a new .pot to Launchpad just now (first time for me!).
If you're a translator for the Miro application, please take a look at the languages you translate for and update them accordingly.
We're planning to do a Miro 1.2.3 release in a week or so. The changes since Miro 1.2 are minimal, so this allows existing translations to improve for the 1.2.3 release.
