> I am getting various flavors of the same exception, and I have to say I have not been
able to reproduce the exact same exception twice. These exceptions seem to be related to adding
a feature to a distribution and then clicking on a bundle. Sorry I am unable to be more specific,
I keep trying to reproduce and then get a new exception each time.
