Environment: Ubuntu 16.04 + Plone 5.0.4 (both zeo and standalone run into the same issue)
Issue: After adding a new page, revisiting the page link will crash the instance.
See this video for reference:
Anything needs to be fixed before we can avoid such issue on Ubuntu 16.04?
Note: it works well when I try Plone 5.0.4 zeo on Ubuntu 14.04.
