Investigate if this is true!

While you're at it, add more debug info:

    DEBUG_PRINTF(
            "Created data channel: label=%s, type=%d, reliability-parameter=%"PRIu32", "
            "protocol=%s, negotiated=%s, id=%"PRIu16"\n",
            parameters->label ? parameters->label : "n/a",
            parameters->channel_type,
            parameters->reliability_parameter,
            parameters->protocol ? parameters->protocol : "n/a",
            parameters->negotiated ? "yes" : "no",
            parameters->id);
