ejabberd epam not working after latest update (15.11 -> 16.01)

After the latest update, ejabberd has started throwing crash messages like these:

The error is pretty obvious:

Can't open file "/usr/lib/ejabberd/priv/bin/epam": enoent

After the latest update, a lot of stuff was changed in the packaging:

[2016-01-20 23:44] [ALPM] warning: /etc/ejabberd/ejabberd.yml installed as /etc/ejabberd/ejabberd.yml.pacnew
[2016-01-20 23:44] [ALPM] upgraded ejabberd (15.11-1 -> 16.01-2)
[2016-01-20 23:44] [ALPM-SCRIPTLET] !!! ejabberd user changed to predefined jabber(uid=17)
[2016-01-20 23:44] [ALPM-SCRIPTLET] !!! check file permission and ownership in
[2016-01-20 23:44] [ALPM-SCRIPTLET] !!!   /etc/ejabberd/
[2016-01-20 23:44] [ALPM-SCRIPTLET] !!!   /var/{lib,log}/ejabberd/

I did go ahead and fix all those things, however another unmentioned change is that the path of ejabberd changed to /usr/lib/ejabberd-16.01 from /usr/lib/ejabberd - so perhaps the internal database (Mnesia) has a reference to the file on this old location? I see no reference to /usr/lib/ejabberd in any of the configuration files in /etc/ejabberd.

Since I'm no Erlang expert, I'm not sure how to fix this the right way. However, as a band-aid, I've just symlinked the old directory to the new directory:

# ln -s /usr/lib/ejabberd-16.01 /usr/lib/ejabberd

Of course this too much of a hack and too little "Arch", so I would like to have some advise on how to fix this issue the right way.
