No reports are shown for the SRU version in

https://errors.ubuntu.com/problem/f74709b604cdae437acbd6591fe8933bc3d8750a

Nor for the cosmic version where we provided the same fix, so I think we
can mark this as verified.

[Timo Aaltonen]

Hello Jack, or anyone else affected,

Accepted gnome-shell into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/gnome-
shell/3.28.3-0ubuntu0.18.04.3 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

We don't seem to have any upstream bug link here, but we also haven't
seen any reports of this crash in 3.27. Looking good so far.
