I had similar issues having several buildbot category waterfall
I cannot remember for the life of me which one of these fixed the issue,
but here is a rundown of my working setup.

1 Waterfall is configured with all the categories on port BASE_WATERFALL
( port 8022 ) its one huge page and very messy, but I think its needed.

Additional waterfalls are specified with each of their categories on
ports BASE_WATERFALL + an offset

The buildbot URL configuration in my master.cfg is 

C['buildbotURL'] = "http://buildbot.mydomain.com:/All/"

My Apache configuration for the Virtual Host "buildbot" contains ... 

    ProxyPass /All/ http://myserver.mydomain.com:8022/
    ProxyPassReverse /All/ http://myserver.mydomain.com:8022/

    ProxyPass /Trunk/ http://myserver.mydomain.com:8023/
    ProxyPassReverse /Trunk/ http://myserver.mydomain.com/8023/

    And so on for each waterfall 

I additionally have some redirects like

Redirect /Trunk http://buildbot.mydomain.com/Trunk/
Just to allow people to go to the status page without the need for the
trailing /

I think the solution comes from a combination of the  c['buildbotURL']
being having an extra level from the base URL , and the Fwd and Reverse

As a warning I do not have to be secure on my server as it is only
accessed from an internal network, hence I cannot make any statement as
to the security of using the ProxyPass declarations.

I hope this helps.
