Internal Error on any RepositoryPage error

[paulsputer]

An internal error page is returned when an error occurs on any page that extends RepositoryPage. Easily repeatable error is login attempt with incorrect password.

Expected result is a red error message box which appears correctly on other pages.

Stack Trace:

A child with id 'projectTitle' already exists:
[Page class = com.gitblit.wicket.pages.SummaryPage, id = 13, version = 1, ajax = 0]
java.lang.IllegalArgumentException: A child with id 'projectTitle' already exists:
