It was just an oversight that we didn't add profile_init_vtable to the
libkrb5 export list.  As Ben said, it should be fixed in 1.12.2.

At the moment, yes.  I would like it to be possible to create an
in-memory empty profile and then set values on it with
profile_add_relation, but we haven't implemented it yet.
