--- Comment #2 from Arun Raghavan <arun at accosted.net> ---
We have the root cause of this bug. The options are to revert the offending
patch for 9.0 (leaving the underlying problem unaddressed, but this is not a
regression). The alternative is to look at merging my patches to drop json-c as
a dep soon. Root cause from email discussion follows:

Okay, so this is a fun one. The offending commit is:

  commit 12a202c510dcacbd2b85fcc1170484eb16fef491

      format: Make pa_format_info_valid() stricter for PCM

      We should do stricter validation when we can.

The check fails at:

  if (json_object_get_type(o) != json_type_string) {
      pa_log_debug("Format info property '%s' type is not string.", key);
      json_object_put(o);
      return -PA_ERR_INVALID;
  }

Rhythmbox and Totem are linked to the json-glib library which *also*
has a json_object_get_type(). That is the function which gets called,
and returns a junk type which makes this code fail.
