IMHO this is a util/server issue:

tcp uses:
GNUNET_SERVER_connect_socket

During plugin unload:
- GNUNET_SERVER_destroy
- GNUNET_SERVER_client_disconnect
- GNUNET_CONNECTION_destroy
- GNUNET_NETWORK_socket_close
  GNUNET_free_non_null (desc->addr); <- CRASH

Might be fixed, SVN was possibly from much earlier than the submission time.

Client is disconnected, MST is destroyed and GNUNET_SERVER_Client *client already freed.

Then we receive incoming data...

I don't see this any more, any many bugs were fixed in this area.
