When I was renaming a configuration, QuickBuild threw a following error. Then I found that this name was already used by another configuration under the same parent. I think QuickBuild should return a message such as "This name has been used by another configuration under the same parent" instead of throwing the DB error.
 Please look into as your earliest chance.

 Thanks,
ptrinh
