Bug ID: 437975
Summary: kded5 crashes in a loop after big update on neon
unstable
Product: neon
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Packages Unstable Edition
Assignee: neon-b...@kde.org
Reporter: bugsefor...@gmx.com
CC: j...@jriddell.org, neon-b...@kde.org, sit...@kde.org
Target Milestone: ---
SUMMARY
After several days without updates on neon unstable, I installed a
big update (~1 GiB) a few minutes ago. Since then 4 drkonqi process
run all the time, causing high cpu usage and making my system unusable.
coredumpctl reveals that kded5 is crashing in a loop.
