gtkpod spews critical error messages:

[Forest]

When I start gtkpod, it prints the followin messages:

** (gtkpod:5585): CRITICAL **: pm_add_all_itdbs: assertion 'itdbs_head' failed

(gtkpod:5585): Gtk-WARNING **: MenuMusic: missing action menuMusic

** (gtkpod:5585): CRITICAL **: file ../../../src/itdb_playlist.c: line 503 (itdb_splr_eval): should not be reached

That last message is printed hundreds of times between launch and exit.

This is gtkpod 2.1.4-1ubuntu2 on Ubuntu 14.04 (trusty) amd64.
