Putting this under FlaggedRevs, but it's really an extension interaction issues that probably requires some discussion on how to resolve it.
Translatable pages (using the Translate extension) cannot be edited, because they are aggregated from text parts that are put into a template. preventDirectEditing() in extensions/Translate/tag/PageTranslationHooks.php. Because I cannot edit the page (no one can actually), FlaggedRevs refuses to allow me to approve any revisions.
I think the expected behaviour here would be for FlaggedRevs to allow me to approve stable versions.
Something's gotta give, but what/how? :)
