[Evolution] Contacts freezing for duplicate File_under instead of merge screen

[Bill Shankly <bill shankly stledger com au>]

Is anyone else finding that contact merging is not working in Evolution
3.13.4 on Ubuntu 14.04 LTS or anything else?

We're finding that on trying to create a contact with a duplicate "File
under:" label, instead of the normal merge screen, the contacts screen
& evolution is freezing.

The only debug info I'm getting (CAMEL_DEBUG=all) is:

(evolution:1929): GLib-GObject-WARNING **: cannot register existing type 'EABContactDisplay'
(evolution:1929): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed
(evolution:1929): GLib-GObject-CRITICAL **: g_object_new: assertion 'G_TYPE_IS_OBJECT (object_type)' failed
(evolution:1929): GLib-GObject-CRITICAL **: g_object_set: assertion 'G_IS_OBJECT (object)' failed
(evolution:1929): Gtk-CRITICAL **: gtk_container_add: assertion 'GTK_IS_WIDGET (widget)' failed

The repo source is fta/gnome3.

Any suggestions, or should I file a bug report?

Thanks, BS
