You can try prepackaged 0.88

Looks like it is just bugs in code.

Activity calls create_new_toolbar not create_old_toolbar (so, detection
code works) but e.g. self.view_toolbar could be created only in
create_old_toolbar but in foolowed code, it is out of "if"

    if _NEW_TOOLBAR_SUPPORT:
        pass
    else:
        self.read_toolbar.props.sensitive = False
    self.view_toolbar.props.sensitive = False

Well, for me it pretty annoying to code bunch of "if"s, for several
activities I used ported code of new toolbars for 0.82+, see
CartoonBuilder, FlipSticks and Speak on ASLO, but for now I'm not going
to support ported code and is switching to intermediate level libraries
