New crash information added by DrKonqi

plasma-discover (5.10.5) using Qt 5.9.1

- What I was doing when the application crashed:
it was a fresh install and discover crashed upon trying to install chromium

-- Backtrace (Reduced):

It's actually not a duplicate. Just a similar issue.
Comment 6 Nate Graham 2018-01-20 04:14:31 UTC
Should we close this as RESOLVED UPSTREAM, or can/should we work around it here, too?
