Bug ID: 391863
Summary: plasmashell gets in endless loop while screen is
locked
Product: plasmashell
Version: 5.12.2
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: awil...@adelielinux.org
CC: plasma-b...@kde.org
Target Milestone: 1.0
Just saw this on a workstation running Adélie, a Linux distribution built on
musl libc. The frames do return (frame 3; finish shows a return code of -18),
so this isn't a hang, but it seems to be stuck in a loop because every time I
break in, it's the same exact stack trace. Computer was locked with
kscreenlocker at 12 noon for a meeting; just after 14:00 it was unlocked and
like this. The clock widget shows 13:04. No background applications were
running beyond Firefox and Konsole, and it's a stock configuration of Plasma
5.12.2 on a Haswell IGP.
I've taken a core dump but I'd rather not send it unless it would be useful to
debugging; it's very large (5.2 GB).
Note also the CPU and RAM usage of Plasma Shell and D-Bus:
