--- Comment #17 from Andreas Oberritter <obi at opendreambox.org> ---
At a second glance, I realized that the access to uninitialized memory was a
problem caused by an earlier modification made to your patch by myself.

However, the problem I still see is here:

    if (source != NULL) {
      *source = g_strndup (location_start, location - location_start);
      GST_DEBUG ("source ip address set to '%s'", *source);
    }

*source becomes non-NULL, even if the string before '@' is empty. I therefore
added location - location_start > 0 to the condition and set *source to NULL
otherwise.

I currently can't download your raw patch from bugzilla, probably due to a
problem with my local resolver and DNSSEC, so it's hard to apply and modify
right now.
