404 Error when clicking "Sign Out" with categories/all as homepage target
On a fresh vanilla 2.0.17 install, after changing the homepage target to categories/all, the "Sign Out" button in the top bar redirects the user to
which results in a 404. A comparable result occurs when the homepage target is set to categories/discussion. /discussions and /activity are not affected, and redirect correctly.
Is there a workaround or fix for this that I can apply quickly?
