[DRE-maint] Bug#923891: redmine: Cannot login after upgrade to 4.0.1-1

[Soren Stoutner]

Package: redmine
Version: 4.0.1-1
Severity: grave
Justification: renders package unusable

After successfully upgrading to 4.0.1-1, users cannot login.  Pushing the login button does nothing.  No errors are produced in the web interface or the logs.

Firefox's developer's console shows the following error when the login button is pressed.

TypeError: url.indexOf is not a function
