[Akonadi] [Bug 372835] New: Korganizer and Digital Clock/Calendar widget keep forgetting of selected Caldav resources

Bug ID: 372835
Summary: Korganizer and Digital Clock/Calendar widget keep
forgetting of selected Caldav resources
Product: Akonadi
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: DAV Resource
Assignee: kdepim-***@kde.org
Reporter: ***@gmail.com
Target Milestone: ---

Our company CalDav calendar resource contains two calendars called "Personal
Callendar" and "Staff".
I'm not using the personal calendar, so I have it permanently disabled.
But, when I enable the "Staff" calendar, by checking a certain CheckBox in
Korganizer calendar viewer, or in the panel->Digital Clock Settings->PIM Events
Plugin, akonadi (usually) forgets this setting after next plasma session login.
Setting this resource as default in the korganizer doesn't have any effect.

This behaviour has been confirmed on (archlinux) machine of my colleague.
This behaviour (in korganizer) is there since KDE-3.5 or before.
This behaviour is new in KF5 for the new style Digital Clock/Calendar plasma
widget.

Best regards.

I'm having a very similar error (at least I think so):

I put the KDE Digital Clock widget on my desktop, enabled the PIM Events
plugin, selected a few calendars from the PIM Events Plugin tab and all is
fine, eg.
my akonadi/PIM events are listed in the widgets calendar leftclick-popup.

Upon restart though, the popup does not show any events, although all widgets
options are still correct.
After I disable and enable the PIM Events Plugin once, everything is back to
normal.

My guess is, either there is a bug in the Digital Clock widget which causes
plugins to not actually be loaded upon restart or there is a race-condition
between the PIM Event Plugin and akonadi/PIM maybe pushing events before the
Digital Clock Widget or its PIM Events Plugin is ready.
(I'lll test something...)

More details:

* I can confirm, this is happening after logout -> login as with Martin Ottmar
* Adding an event in KOrganizer while the PIM Events Plugin is not working does
not fix it, so it does not seem like a race-condition between Widget/Plugin and
akonadi/PIM.
* OS is Manjaro/archlinux, KDE Plasma 5.8.5, KDE Frameworks 5.30, Kernel 4.9.6
