AttributeError: 'NoneType' object has no attribute 'ticket'

This error only seems to occur when the revision closed a ticket.

I found that removing "formatter.href.ticket(num)" from the following line removes the error.

href = formatter.href.ticket(num) + params + fragment

But it also prevents the closed ticket link from working.

This is a ​bitten issue, not a Trac one.

Please report this error to the bitten project. I'm not sure about the status of Bitten and Trac 0.11 though.
