AttributeError: ScannerError instance has no attribute 'message'

Reported by:	Johannes	Owned by:	malsmith
Priority:	highest	Component:	GanttChartPlugin
Severity:	blocker	Keywords:
Cc:		Trac Release:	0.11

Description

I installed the gantt plugin on trac 012dev. This are the steps I did to install:

Installed Prerequisites:

PyYAML
python-dateutil
Python Imaging library (PIL)

Installation via easy_install (0.11) and uploading the egg in the Admin -> Plugins section.

Cache dir: Created cache directory, made it writable for the webserver, added the following lines to trac.ini:

[gantt]
cache_dir = /path/to/cache_dir

Now, adding test data using that plugin to the wiki results in the following error:

AttributeError: ScannerError instance has no attribute 'message'
