Subject: Calendar: don't initialize the event source synchronously
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~1013^2^2~4812
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=0aa26e91341b667ce23fadce033a4ac4ef0053bc;p=gnome-shell.git

Calendar: don't initialize the event source synchronously

We don't want to block the shell start to load evolution-data-server
and open all calendars (which can involve network connections)
