Rails - Aug 2006 - Bug in ActionPack

I have a controller named "guest_group" with an action
"list" and a
controller named "guest" with an action "group_list".
Internally the
views seem to be cached after converting the ''/'' in the path
to ''_'' ->
there is a clash in my code were an erroneous view (of a previously 
accessed action) is rendered.

Ugly as hell :-)

Is it a known bug? Where should I report it?

Lionel.
