cannot add comment to newly created tickets (ValueError: need more than 1 value to unpack)

[mklerk@…]

I created a new ticket workflow with a triage on the first ticket state using AdvancedTicketWorkflowPlugin. (see workflow below)

How to reproduce:

1. Submit a new ticket
2. Try to add a comment to it.

I get the following error message:

Trac detected an internal error: ValueError: need more than 1 value to unpack

Note that the following plugins seem to be involved: ticketvalidator.core, AdvancedTicketWorkflowPlugin Please report this issue to the plugin maintainer.

After disabling the TicketvalidatorPlugin the problem was solved.

Workflow:
[ticket-workflow]

accept.operations = set_owner_to_self
accept.permissions = TICKET_MODIFY
