Error with Rack fetching session-based cookie

My web app is using Rack 1.4.0, Sinatra v1.2.6, Thin v1.2.11, Ruby v1.9.2p180

Navigating to a page I get this error in the log:

TypeError - can't convert nil into String:
 /usr/local/lib/ruby/gems/1.9.1/gems/rack-1.4.0/lib/rack/session/cookie.rb:152:in `hexdigest'

 /var/www/phrogz.net/routes/test.rb:8:in `logged_in?'

The code in test.rb line 8 is:

session[ :foo ] == "BAR"

Any suggestions on what to upgrade/downgrade to fix this?

Looks like you run into this issue. The fix is in Rack 1.4.1 so simply upgrading should fix it.
