Occasional crashed after login

[handsome_feng]

OS: ubuntu kylin 23.10 beta
version: ukui-settings-daemon 3.1.1.1-3

1. login UKUI
2. Occasional show windows that "UKUI Settings Daemon Crashed"
3. Got crash file in /var/crash

Not 100%, but the probability is very high, and the process can restart automatically, and then everything seems fine.

Hey there! Thanks for preparing the fix (and uploading it) but I think this would be a good fit for 0-day SRU instead of letting in it now and then doing another re-spin.

[Andreas Hasenack (ahasenack)]

This bug is ready for verification. Due to the status mantic was in when the package was accepted, the tooling failed to add the template comment to this bug, and add the tags, and I did all of that manually now.

Hi, friendly ping that this bug is waiting verification.

[handsome_feng (feng-kylin)]

Hi, I have verified ukui-settings-daemon 3.1.1.3-3ubuntu1 works fine in mantic.

[Brian Murray (brian-murray)]

This looks similar to the following crash in the Ubuntu Error Tracker and we can see that the new version of the package in mantic doesn't appear in the affected versions table.
