Comment 2 for bug 1538277

Fixed in the trunk, rev. 14918.

I have removed the inkex.localize() call from the extensions, but the change won't break custom extensions that still use it (it can be called several times with no issue).

Thanks for your suggestion, ~suv. Not only it solves the issue, but the extensions are a bit cleaner and easier to maintain. I'm still wondering why I didn't implement it from the beginning ;)
