Well after some additional testing, it seems that the issue is with editing static pages with the advanced editor.
That's odd since the static pages plugin has its template files in the plugin directory, so all the themes should use the same templates ...
However, if the theme directory contains a "staticpages" directory, then the templates from that directory are used. So check the non-working themes and if they have such a directory, simply remove it.
