So, I am getting this error on my SharePoint servers (Running Windows 2008 SP2).
( Blog 1, and Blog 2) that describe "fix" by doing the following:
1. Navigate to /14/ControlTemplates/TaxonomyPicker.ascx user control
2. Open the user control in a text editor and locate the first line
3. Find the character string , and replace with a comma ‘,’ (without quotes).
4. Save the user control and you have completed fixing this bug
I am not sure I want to do this at this point, since this action seems a hack to me and Microsoft my release an update to fix the issue.
In short, I can live with this error till Microsoft release either a KB article or an update for this issue.
