Indeed. Unfortunately, I will not be able to take a look until January.

IPA-CP is decrementing reference count of parameter 1 instead of
parameter 2.  That happens because the variable param_index in
ipcp_discover_new_direct_edges has type bool instead of int.  What a
stupid mistake.  I'll prepare a patch.
