Subject: Plug some memory leaks and an invalid read
X-Git-Url: https://code.delx.au/pulseaudio/commitdiff_plain/b430407f47fac227b4a6952ab502705d83ff90f5

Plug some memory leaks and an invalid read

Note in protocol-dbus.c specifically, method_signatures needs to be freed
before method_handlers, because otherwise h->method_name is freed while it is
still in use as a key in the method_signatures hashmap.
