errors.ubuntu.com shows this as the current #10 crash in gnome-software.

While there is a bug here, I'm not able to reproduce it and I don't
think it's a high priority to fix.

The likely trigger is a user is prompted for updates through a
notification, they click on it to see the updates dialog and then close
that before it has got the historical update information. This causes
GNOME Software to crash, but given they closed the dialog this is
probably not a big problem. It would launch again when they next tried
to use it.

If the cause is eventually found, this is a good candidate to cherry
pick back to the version of GNOME Software in bionic.

Closing the bionic task as "Won't Fix".
