Delete Contexts via Admin Screen

If you are the user that created the context OR a user that is using a bad context, you can change it by:

• go to chartboard
• select an empty version (this was the only way i found to change the version that you look at in the taskboard, without getting a stack trace), delivery cycle 14 in this project.
• after the chart loads, go to the taskboard
• this will bring up the taskboard, but you will not get a stack trace because there are no tasks
• change the context to a good context, or delete if you are the create user.

Can this be a feature request that a jira administrator is able to delete contexts in greenhopper via some admin screen OR can the application catch the exception and show an empty task board with 'bad context' message to the user?
