errors.ubuntu.com entry:
https://errors.ubuntu.com/problem/a7429d1aa03ffd472182b658004361c9985a4aca

[Robert Ancell (robert-ancell)]

The particular code path only occurs when gnome-software is run with --mode=updated.

[Robert Ancell (robert-ancell)]

This mode is triggered when following an update notification.

[Robert Ancell (robert-ancell)]

The crash occurs when getting historical updates and suggests the dialog was closed before this happened. The only plugin that provides these in Ubuntu is the fwupd one, so I suspect that's either not correctly handling a cancel request when the dialog is closed or GNOME Software is not generating the correct canceled error.

[Robert Ancell (robert-ancell)]

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".
