TypeError when dropping content into an NITF tile

[hvelarde]

Plone 4.3.10 with collective.cover 1.2b1 and collective.nitf 2.0b2 installed.

• create an empty layout
• add an NITF tile
• drag and drop a News Article on it

you'll see an error:

2016-09-12T08:53:02 ERROR Zope.SiteErrorLog 1473684782.270.491508807798 http://example.com/Plone/@@updatetilecontent

we need to test if this happens in the 1.x branch also.

after upgrading to collective.cover 1.3b1 the error is still present.
