I can confirm this error. It looks like there is some iterator running, and when snd_config_search_definition runs, it changes the config tree, because there is some hook that does this.
So the iterator's pointing to already freed memory.
The iterator is probably the one in the add_card function, because it repeatedly runs try_config.
