Yup this is another area where bbpress has to be fixed before it hits the mainstream (or before the mainstream will adopt it).

If you are using it with wordpress, for now you can route all the login/register links to wordpress which does a better job.

I discovered this by accident from the plugin that email favorites which I then had to hack directly to fix.

I’ll open a ticket in trac if there isn’t one already.
