Workflow "user.workflow.72743D30-3F8E-4030-932F-D8806264EAC3" seems to be this one: http://www.packal.org/workflow/files-and-folders
The problem is in the file packal/package.xml, line 3, column 15: use of the character "&". I have corrected the error by replacing "&" with "and" for the name of the workflow and this solves the problem.
