@@oembed-info view only exists for content items

collective/oembed/configure.zcml defines an oembed-info view for Archetypes and Dexterity content type objects:

```


```

Our Funnelback search engine is finding oembed discovery links in other places, for example on:

http://www.ucs.cam.ac.uk/++contextportlets++plone.rightcolumn/uis-jobs

I have worked around this by adding a fallback/default view for all objects:

```

```

However I think that collective/oembed/provider.py

```
class OEmbedProvider(BrowserView):
...
def add_context_info(self, ob, site):
....
info = ob.restrictedTraverse("@@oembed-info")()
```

should probably catch AttributeError exceptions.

Start in collective/oembed/provider.py at OEmbedProvider.add_context_info and inspect the restrictedTraverse("@@oembed-info") call. Review collective/oembed/configure.zcml to compare the registered view interfaces, then verify that discovery processing handles objects without that view as intended, including the portlet URL example.
