Build definitions, notifiers erroneously lost or deleted if created during initial checkout

Immediately after a project is created, and the project name clicked on, an automatic checkout happens. If the project is large, this checkout may take some time to complete. During the checkout, build definitions and notifiers may be added using the normal web interface. HOWEVER, these build definitions and notifiers disappear once the checkout completes.

To reproduce the problem:
1. Create a new (shell) project that does a large checkout.
2. While the automatic checkout is proceeding, create a build definition and/or a notifier.
3. Wait until the checkout completes.
4. Refresh the view of the project - what happened to the build definition and notifier?!

Workaround:
Create the build definitions and notifiers AFTER the initial checkout completes.
