render partial in views root failing to find template

Hi, I upgraded to edge rails (svn revision 9250) and found this problem. I had "menu" partial, stored inside /app/views/_menu.html.erb. I call it from another template, using this code:

<%= render :partial => "/menu" %>

It worked ok in 2.0.2, but when running it on edge rails, it fails with this message: "Couldn't find template file for _menu in ["...../app/views"]"

I found a workaround. I moved the partial template to views subfolder /app/views/newsubfolder/_menu.html.erb and call it using

<%= render :partial => "/newsubfolder/menu" %>

and then it works. But don't want it to be in subfolder.
