evolution crashed with SIGSEGV

[Stefan Hoppe]

Impact
-------
The new/edit email dialog in Evolution crashes the app when it is closed.

Test Case
---------
Install the update
Open the Settings app. Click the About button at the bottom of the left sidebar (you may need to scroll down to see it). Verify that the Windowing System is Wayland.
Open Evolution.
Click the New Email button.
Add some text to the draft email.
Close the dialog.
Choose Discard.
The edit email window should close but Evolution should remain open.

Regression Potential
--------------------
One line fix to stop a really annoying crash by disabling hardware acceleration.

The webkitgtk and Ubuntu Desktop developers suspect that switching webkit2gtk to build with the wpebackend will avoid this crash, but it requires main inclusion for additional libraries. The main inclusion will be worked on over the next few months.

[Brian Murray (brian-murray)]

Hello Stefan, or anyone else affected,

Accepted evolution into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/evolution/3.44.0-1ubuntu1 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, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. 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.

I installed evolution 3.44.0-1ubuntu1 and verified that I was able to use the New Email dialog without it crashing and with it showing my text on the default Ubuntu (on Wayland) session.

[Launchpad Janitor (janitor)]

This bug was fixed in the package evolution - 3.44.0-1ubuntu1

---------------
evolution (3.44.0-1ubuntu1) jammy; urgency=medium
