I was installed jsgantt-plugin-0.9 based on trac-0.11,but i get some error: ERROR: Macro TracJSGanttChart(milestone=Test) failed userstart The trac.log is :

2011-09-01 07:45:11,995 Trac[formatter] ERROR: Macro TracJSGanttChart(milestone=Test) failed

KeyError: u'userstart'

next is the configuration in trac.ini

[trac-jsgantt]
  # To work with Timing and Estimation for percent complete
  fields.estimate = estimatedhours
  fields.worked = totalhours
  # Each unit in estimate is 1/8 of a day
  days_per_estimate = 0.125

  # Custom fields for start and due dates
  fields.start = userstart
  fields.finish = userfinish
  #
  date_format = %Y-%m-%d
  milestone_type = milestone

I think it different with #8859

I configured userstart in my trac.ini and I do not see this behavior. If the OP reads this, please post your custom field configuration for userstart.
