Released Zope Updater Tool Version 1.3.1.
Due to pysvn repeatedly calling the authentication function if you typed your username or password incorrectly it would tie up a zope thread until it was restarted. Made changes so that the authentication information only gets used once and an error happens if the function gets called a second time. This solves the zope going into an infinite loop.
pysvn doesn't provide a way to know that authentication failed so I have to assume that every ClientError is a mistyped username or password.
