This shouldn't be marked as a duplicate of that bug.  It has nothing to do with
POP or Akondai as far as I can tell.

I'm getting crashes of plasma shell as much as several times an hour during
normal use in my Proxmox KVM running Kubuntu 16.04 (just upgraded from 14.04)
with qxl display driver.  I've tried to attach the crash report to this bug but
the crash reporter doesn't seem to want to let me because it's marked as a
duplicate.
