The default theme does not include translation of a few elements. Forinstance the "Posted In" message at the bottom of each atricle should be made translatable. This is found in index.php on lin 17, archive.php on line 46. Also this is true for the Comments/No Comments in archive.php
Also the "is proudly powered by" and the "and" in the footer.php on line 5 and line 8.
There is probably more.. :)
Who is responsible for changing the php and updating the pop file? Should I do it myself and post a bug somewhere?
