Either

if (!g_variant_lookup (...))
  sender = 0;

or pre-initialize it. Otherwise we'll return undefined stack contents if there is a message-sender but its type is wrong.

Inline get_message_edit_timestamp here, maybe? (Non-blocker)

Is supersedes leaked?

Nitpicking: this doesn't copy binary content (it can either be an 's' or an 'ay'; iirc the latter was originally to support vCard over MMS, which sends a binary blob of unspecified encoding, containing embedded charset tags analogous to HTML <meta name="charset">).

I think that's fine for example code, though.

Should be specifically guint32, I think? (Although this is going to be the least of your worries if your platform has non-32-bit ints.)

Sorry, I was unclear.

What I meant was that get_message_edit_timestamp() calls tp_message_dup_supersedes():

 get_message_edit_timestamp (TpMessage *message)
{
- if (tp_message_get_supersedes (message) != NULL)
- return get_network_timestamp (message);
+ gchar *supersedes;
+
+ supersedes = tp_message_dup_supersedes (message);
+ if (supersedes != NULL)
+ {
+ g_free (supersedes);
+ return get_network_timestamp (message);
+ }
else
- return 0;
+ {
+ return 0;
+ }
}

(sorry for the indentation damage, cgit is being invaluable)

and so you could save a malloc/free if you inlined get_message_edit_timestamp into its caller, which already needs to call tp_message_get_supersedes() anyway.

OTOH, if there are other callers, that's more annoying.

I don't see a fix for that?

... because I wasn't looking hard enough. Yes, sorry, you did fix it.
