Merge remote-tracking branch 'public/bug23693_029' into maint-0.2.9

changes/bug23693

+  o Minor bugfixes (relay, crash):
+    - Avoid a crash when transitioning from client mode to bridge mode.
+      Previously, we would launch the worker threads whenever our "public
+      server" mode changed, but not when our "server" mode changed.
+      Fixes bug 23693; bugfix on 0.2.6.3-alpha.
