PulseAudio verbose logs would be helpful, yes. We don't enable them by 
default so there's usually nothing "from the server" unless someone does 
one and uploads it to launchpad.

That said, I wonder what would happen if we did this:

diff --git a/src/daemon/main.c b/src/daemon/main.c
index deb1e43..039957f 100644
--- a/src/daemon/main.c
+++ b/src/daemon/main.c

      if (c) {

is still ref'ed,
           * as unlink callback hooks in modules may need the core to be

+        c->disallow_module_loading = true;
