Comments: I also run into this problem in my project. What I don't understand is, in work item #27149, Superexpert (who closed that work item) said that this was fixed with September 2012 release. Now this bug re-appeared in April 2013 release? I'll try the easy fix mrflo suggested. Hope this can be fixed in the next release soon.
