evolution/shell/evolution-shell-component.c
T
Ettore Perazzoli 611fbb0443 Increase the default value for 
* apps_evolution_shell.schemas: Increase the default value for
/schemas/apps/evolution/shell/view_defaults/folder_bar/width to
200. 	[#41002]

* evolution-shell-component.c (owner_ping_callback): Enable this
again.
(setup_owner_pinging): Same.
(impl_setOwner): Check if the shell is in-process and, if so, call
setup_owner_pinging().
