As the error mentioned by mafen is related to this bug but is slightly different. It is caused by the upgrading of the wallpost block data so I'll make a new bug report to deal with this issue.

As upgrade is run by user id = 0 we can ignore the institution check for them (they won't have any institutions anyway).
