Bug#885023: gnome-shell: spams syslog with "e_cal_recur_generate_instances_sync: assertion 'icaltime_compare (interval_start, interval_end) < 0' failed"

Fri Dec 22 23:09:39 UTC 2017

Package: gnome-shell
Version: 3.26.2-1+b1
Severity: normal

Fills syslog. Not nice. Started occuring on my desktop system, running 
mostly testing,
sometime in the last few days, perhaps today. Let me know if there's 
anything I can
do to help diagnose/fix this.

Example:
