LDAP importer fails silently when no location is explicitly entered for the new model

LDAP import fails silently when no location is entered for the "Source Model Definition" section's "Location" field on the first page of the wizard. This occurs even when using the context menu to initiate from a specific project or child object level. The wizard functions as expected until you finish, at which point the model is never generated. No error dialog or failure notification is presented to the user. checking error log shows:
