Bug#824390: gnome-shell-calendar-server gets SegFault after stack smashing detected

Package: gnome-shell
Version: 3.20.2-1
Severity: normal

After the last upgrade (from version 3.18) I noticed an high CPU utilization for gnome.shell.
This seems to be related to the process gnome-shell-calendar-server crashing and being restarted continuously.
Running the process within a debugger provides this output:
(gdb) run

(But due to probable stack corruption and lack of debugging symbols I don't think this so meaningful)

I can provide also a core dump, if needed.
The warning about the missing data source object is a warning due to my evolution configuration being very old (some glitch in an upgrade back in gnome2 i think) but it never led to probems.
