Bug ID: 433192
Summary: System Settings on Wayland aborted when clearing
history of activities with a failed dbus assertion
Product: systemsettings
Version: 5.21.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_activities
Assignee: ivan.cu...@kde.org
Reporter: matthew.fagn...@utoronto.ca
CC: plasma-b...@kde.org
Target Milestone: ---
SUMMARY
I was using Plasma 5.21.0 on Wayland in a Fedora 34 KDE Plasma installation
with KF 5.79, Qt 5.15.2, Mesa 21.0.0-rc4. I started System Settings. I entered
activities in the search bar and selected Activities in the left bar. I
selected Privacy in the Activities screen. I had previously set Keep history: 1
month and Remember opened documents: Do not remember. I selected the Clear
History box and Forget Everything. System Settings aborted with a failed dbus
assertion 'arguments to dbus_message_new_method_call() were incorrect,
assertion "_dbus_check_is_valid_path (path)" failed in file
../../dbus/dbus-message.c line 1366.' as shown in the following journal output
at the time of the crash.

[Inferior 1 (process 6689) detached]
The crash happened 3 of 3 times I tried to clear the history of activities as
above.
STEPS TO REPRODUCE
1. Boot a Fedora 34 KDE Plasma installation updated to 2021-2-19.
2. Log in to Plasma 5.21.0 on Wayland
3. Start System Settings
4. search for Activities in the search box.
5. select Activities in the side bar
6. select Privacy in the Activities screen.
7. set Keep history: 1 month
8. set Remember opened documents: Do not remember.
9. select the Clear History box
10. select Forget Everything
OBSERVED RESULT
System Settings on Wayland aborted when clearing history of activities with a
failed dbus assertion
EXPECTED RESULT
No crash would happen.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 34
(available in About System)
KDE Plasma Version: 5.21.0
KDE Frameworks Version: 5.79.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
drkonqi crashed twice when I tried to report this problem when entering a
description. The system is using dbus-broker-26-2.fc34. dbus-1.12.20-3.fc34 is
also installed.
