Description Jeremy Bicha 2017-05-10 19:19:03 UTC 
Ubuntu has received some semi-automated error reports from Ubuntu 17.04 with this crash signature. The crash appears new to gnome-calendar 3.24.1.

This error is one of several keeping gnome-calendar 3.24.1 from reaching all Ubuntu 17.04 users because Ubuntu has a phased-update system for users who install updates using Ubuntu's update-manager tool.

gnome-calendar (11) gcal_manager_set_search_subscriber → gcal_search_view_do_search → g_timeout_dispatch → g_main_dispatch → g_main_context_dispatch

Also happens on Fedora 26, same backtrace: https://bugzilla.redhat.com/show_bug.cgi?id=1450618

Created attachment 352586 [details] [review]
proposed patch

The search view doesn't have set the manager, then there are several runtime warnings on console, then eventual NULL dereference. This one-liner fixes it for me.
