Bug ID: 430739
Summary: Re-login to Wayland session fails possibly due to
kded5 crash
Product: plasmashell
Version: master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: bugsefor...@gmx.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
If I try to restart Wayland session immediately after logout from it,
login fails and coredumpctl command lists kded5 coredump.
STEPS TO REPRODUCE
1. start Wayland session
2. logout
3. immediately try to login to Wayland session again
OBSERVED RESULT
Wayland session is not started and kded5 coredump is generated.
This problem does not occur if I wait ~30 seconds before trying to log in
again.
EXPECTED RESULT
login to Wayland session without any coredump
