* we cannot set strings in struct, see GTK bug [https://bugzilla.gnome.org/show_bug.cgi?id=678401]
* error in list_families on textview in styledtexteditor: [https://bugzilla.gnome.org/show_bug.cgi?id=679654]
* str and unicode no longer seem to work, the encoding must be passed too; '''Future: deprecate unicode() in the code, as we want to support python 3'''
* there is no longer automatic conversion to str utf-8 when using GTK functions, we must convert before passing to GTK.
* glade can no longer work with our catalog. We need to upgrade comboboxentry to combobox with has_entry manually, and hope editors keep working... - '''SOLVED:''' converted editevent.glade, all works
