Description of problem:
Many errors are being reported from translate.zanata regarding account/login_input.xhtml.
As far as I can tell, this file does not exist (unless automagically created) in Zanata's code base and is only referenced in zanata-war/src/main/webapp/WEB-INF/urlrewrite.xml

Is this a bad url rewrite, somehow?
The "sudden frequency" implies that someone is trying furiously to log in with limited success.

Version-Release number of selected component (if applicable):
3.4

How reproducible:
Unknown - comes from error logging

Steps to Reproduce:
-
