crash when trying to create new project based on template

[davidstern]

I defined a series of templates for projects. There is a button in the detailed view (tab administration) of a project template to create a new project based on that template. When I use it, this is the message I get:

ProgrammingError: syntax error at or near "27"
LINE 1: update project_task set active=True where project_id in 27

I tried with different protocol and client, but still the same behaviour.

This is the whole message:
