I'm experiencing this crash on exiting Basket-kde5port, not sure about the reason:

Status changed to 'Confirmed' because the bug affects multiple users.

[Peter Wu (lekensteyn)]

Same problem with exiting Wireshark (wireshark-qt). Would a SRU be possible with this change:

[Peter Wu (lekensteyn)]

This (upstream) patch was merged into Breeze v5.8 but applies cleanly on v5.5.5 (in the repos).

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "[PATCH] Fix crash on exit" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

@ Peter Wu – the link doesn't work. This should be right:

https://cgit.kde.org/breeze.git/commit/?h=Plasma/5.7&id=23e54baa3cf1258b5d105c22609103d13868583f

Thanks for looking into that!

@ gl.bars:

Pls read carefully -> https://wiki.ubuntu.com/Bugs/Bug%20statuses

If a bug is fixed upstream it'snot likewise here in launchpad, as if nothing has happend within in Ubuntu.

[Scarlett Gately Moore (scarlettmoore)]

This is very old, if it is still an issue, please update the bug with info on a supported release.
