JC> epiphany is using automatic debug packages:

Ah, a new invention. OK I'll try them...

JC> For the accessibility messages, I suppose you don't have at-spi2-core

JC> Recommends dependency.  I don't know about the others messages.

Reportbug says
Versions of packages epiphany-browser recommends:
pn  browser-plugin-evince  <none>
ii  ca-certificates        20161130+nmu1
pn  evince                 <none>
ii  yelp                   3.22.0-1

epiphany-browser suggests no packages.

so at-spi2-core is nowhere in any of them.

But OK I'll install it.

And indeed the accessibility warnings finally have gone away!

So please make at-spi2-core a Depends,

or: make it less than a Depends, and be sure the warning says what the
user should do.
