Bug ID: 435097
Summary: 30s Frozen Start (timeout) of Dolphin, Gwenview, etc.
caused by kactivitymanagerd
Product: kactivitymanagerd
Version: 5.21.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
After last update of arch to 5.21.3 there is a problem with starting of KDE
applications like Dolphin, Gwenview, System Settings etc. The problem happens
that the KDE apps are called in Gnome, Awesome or other environments/WMs.
Directly the bug is not visible in KDE env.
I spent 2 days on the analysis this bug. To compare all processes which are
started or not. The problem is in coop with process:
/usr/lib/kactivitymanagerd
If this process is not started, or it is partial started, the 30s timeout on
start apps happen.
This is critical bug which cause bigger problems in other env/WMs.
STEPS TO REPRODUCE
1. use KDE apps Dolphi, Gwenview, System Settings etc. in any other env/window
managers.
2. the application is not started, wait 30-35s
3. the application is shown.
OBSERVED RESULT
Problem is that the /usr/lib/kactivitymanagerd is not normally started in any
other envs. This is bigger change and dependency on internal deps in KDE. This
doesn't belong to KDE API apps.
EXPECTED RESULT
Remove this dependency and timeout on /usr/lib/kactivitymanagerd. The
cooperation has to be handle by different way.
