Redmine

Since Redmine 0.8.7 there is some problem at login (it's impossible) when running in a tomcat servlet container via jruby.

while up to 0.8.6 things work fine just as described here: http://www.redmine.org/wiki/redmine/HowTo_install_Redmine_in_Apache_Tomcat, in 0.8.7 I get the following error in the tomcat logs(for plain tomcat from apache) or in the webbrowser, after I enter my username and password in the login form:

Also, running jruby script/server starts up a working Redmine system.
