[Evolution] WARNING error messages

[Ross Boylan <ross biostat ucsf edu>]

I'm seeing quite a lot of chatter in the terminal from which I launch
evolution 1.4.4.  Here are some samples:
(evolution:926): widgets-WARNING **: Could not open converter for
'X-UNKNOWN' to 'UTF-8' charset


(evolution:4476): GLib-GObject-WARNING **: value "-1.000000" of type `gdouble' is invalid for property 
`clip-height' of type `gdouble'

(evolution:4476): gtkhtml-WARNING **: Cannot create spell dictionary instance 
(iid:OAFIID:GNOME_Spell_Dictionary:0.3)

(evolution:4476): Bonobo-WARNING **: Activation exception 'Failed to activate 
'OAFIID:GNOME_Spell_Control:0.3''
[the next few make some sense: I tried to open my contacts without having a default set]
(evolution:4476): EBook-WARNING **: e_book_load_uri: Unable to determine protocol in the URI


(evolution:4476): EBook-WARNING **: e_book_unload_uri: No URI is loaded!

Should I just ignore these, or should I file bugs?  The frequency of
them does seem to be going down.
