Does anyone get a 'That was unexpected' error message when trying to view content on the community?

Occasionally our users get a message saying 'That was unexpected...' when browsing our community.

Has anyone seen this message or is it possible it is unique to our configuration.  If anyone has seen this do you know what the cause is?  I check the logs and see messages but am not sure if they are related.
