8859,ERROR: Macro TracJSGanttChart(milestone=...) failed,bobrien@…,Chris Nelson,"Running trac 0.12 with the latest version of the TracJsGanttPlugin (installed using easy_install this morning).  Regardless of whether any other coordinating plugins are installed or not (such as mastertickets, subtickets, timingandestimation), I cannot make a gantt chart display from a very simple existing milestone in Trac (10 tickets, 2 closed, backend repository is Mercurial).  

Currently, only tracjsgantt.* is enabled in my trac.ini file, and no [trac-jsgantt] section is defined (all commented out) - see Debug output below.  If I try adding back certain fields (as outlined on the TracJSGanttPlugin wiki page), I get different, but similar, errors - issues like: 

TypeError: strptime() argument 1 must be string, not int.

and

KeyError: u'userstart'

I'm just trying to display a gantt chart, nothing fancy (yet).  Looking through the other active tickets there appears to be some question whether this plugin works with Trac 0.12.  Is that accurate?

From the trac.log file in DEBUG Mode:
