actions without operations cause errors in text mode

I was testing with the text mode and the opensource workflow from trac's contrib workflows and I noticed errors of the form

2012-10-17 17:38:35,718 Trac[main] ERROR: Internal Server Error: 
Traceback (most recent call last):
  File "/path/to/trac/web/", line 497, in _dispatch_request

    if 'leave_status' in act['operations'] and act['next'] == '*':
KeyError: 'operations'

It would appear that trac is happy for some actions to lack an operation and so I suggest something equivalent to the following:

  • tracworkflowadmin/

    511511        if len(errors) == 0:
    512512            leave_status_exists = False
    513513            for act in params['actions']:
    514                 if 'leave_status' in act['operations'] and act['next'] == '*':
     514                if 'leave_status' in act.get('operations',[]) \
     515                        and act['next'] == '*':
    515516                    leave_status_exists = True
    516517                    break
    517518            if not leave_status_exists:
