Hi,
I am not sure if this is just us, or it is really a bug.
I have tried version 2013073000 on 2.4.6 and 2.5.2

When users receive those emails:
emailoncompletebodyown
You have completed checklist '{$a->checklist}' in the course '{$a->coursename}' View the checklist here:
or
emailoncompletebody
User {$a->user} has completed checklist '{$a->checklist}' in the course '{$a->coursename}' View the checklist here:

they get this URL generated by {$a->checklist}
http://blah.com/mod/checklst/view.php?id=55555

the I is missing in checklst, so once they click - they get an error

Thank you for looking into this
