Why is the pid used here? I don't understand why this helps. If
additional instances are created in this process then the name won't be
unique. The name isn't exposed outside the process, so there is no need
to uniquely identify the process either.

g_free(busname) is missing. A nice way to fix this is:

  g_autofree char *busname = ...

This avoids the need to manually call g_free().
