------- Comment #3 from Stefan Kost (gstreamer, gtkdoc dev)  2008-09-05 13:16 UTC -------
strcmp crashes if either argument is NULL. As this is the code, the only
explanation would be pspecs->data==NULL. This would mean that the v4lsrc or
v4l2src have no "device" property. For now I added a check for pspec!=NULL. Not
sure what to do with the bug though.

const GParamSpec *
gst_property_probe_get_property (GstPropertyProbe * probe, const gchar * name)
{
  const GList *pspecs = gst_property_probe_get_properties (probe);

  g_return_val_if_fail (probe != NULL, NULL);
  g_return_val_if_fail (name != NULL, NULL);

  while (pspecs) {
    const GParamSpec *pspec = pspecs->data;

    if (!strcmp (pspec->name, name))
      return pspec;

    pspecs = pspecs->next;
  }

  return NULL;
}
