I traced down the problem to one single call to the function "g_thread_init()" inside the package "pidgin-skype". As of the official glib documentation [1], the function is not needed anymore and it is deprecated from version 2.32 on, and apparently is disabled when telepathy-haze and empathy try to load the plugin.
I'm attaching a patch that comments out the call to g_thread_init. As far as I have tested it seems to work fine.
