I am polishing up the 2017.ploneconf.org site so that I can use httrack on it to generate a static copy, to be served instead of the Plone site.
When I rebuild the catalog, I get a POSKeyError, which I tracked down to the page https://2017.ploneconf.org/talks/talks. If you scroll down to the end of the keynotes and before the normal talks list, you can see that a tile renders with There was an error while rendering this tile
Looking with the wayback machine, that tile is a simple decorative one: https://web.archive.org/web/20171001014802/https://2017.ploneconf.org/talks/talks
The POSKeyError prevents edits to the page, with the error stack:

I tried to mess with /usr/local/plone-5.0/buildout-cache/eggs/plone.app.textfield-1.2.8-py2.7.egg/plone/app/textfield/value.py https://github.com/plone/plone.app.textfield/blob/1.2.8/plone/app/textfield/value.py#L56 and have it return a simple string if it caught a POSKeyError, but that doesn't seem to work; something above in the call stack may be swallowing the exception:
@property
def raw(self):
from ZODB.POSException import POSKeyError
try:
return self._raw_holder.value
except POSKeyError:
return 'POSKeyError!!!'
I'd like to make it possible to edit the page to delete and recreate that decorative tile, or at least be able to rebuild the catalog.
Help! 
Thanks!
