[Mediawiki-l] Blank page when login password wrong

[Jeff Campbell]

We just installed version 1.17 on our system. (sun, solaris) and find if 
someone goes to log on and enters the wrong password they get a blank 
page. If they try to log on and just don't put a password in you get  
this page: 
http://www.xxx.org/wiki/index.php?title=Special:UserLogin&action=submitlogin&type=login

  Is this a bug or do I have something set up wrong? I looked through 
the bug tracker but saw no bugs of this.
