Bug ID: 359611
Summary: Plasmashell loads itself incompletely and with long
delays
Product: plasmashell
Version: 5.5.4
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: eugene.shalygin+bugzilla....@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Loading of the plasnashell takes more than minute. If I interrupt it when I/O
activity stops, gdb shows the following backtrace:

If systemtray is removed from the panel, the Plasma (re)loads in a few seconds.
The adding of the systemtray takes the same minutes (with the same backtrace)
as loading plasma with it.
And there are no "Suspend" and "Hibernate" actions in the launcher menu whether
plasmashell contains systemtray or not.
Reproducible: Always
Steps to Reproduce:
1. login to Plasma or kill and start plasmashell
$ qdbus command executes without delays
