evolution freezes/soft deadlocks time to time on X11
While I surf through my emails and deleting them, evolution user interfaces freeze from time to time. Then it either fixes itself (most probably related to a network/time-based event) or when I switch window.
I even tried to collect backtrace with dbg, with the following command:
sleep 10; echo now; gdb --batch --ex "t a a bt" -pid=
pidof evolution &>bt.txt
but as soon as it echoes the now, the evolution woke up, making it impossible to collect evidence in this way.
Evolution is 3.36.4-2 (Debian testing) running on an amd64 system. The freeze happens very often, sometimes even after 1-2 actions, but sometimes I can delete tenish mail before it happens again.
