Bug ID: 495101
Summary: KDE Connect Notifications May Cause Plasmashell to
Freeze
Classification: Applications
Product: kdeconnect
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: plasmoid
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Summary
When waking up a computer with KDE Connect enabled and receiving multiple
notifications from a phone, plasmashell may freeze while waiting for data from
KDE Connect. This likely happens because KDE Connect stalls when sending the
notifications to plasmashell.
Steps to Reproduce
Put a KDE-running computer to sleep.
Receive several notifications on an Android phone (including a call), leaving
them in the phone's notification tray.
Wake up the computer to trigger the notifications being sent to KDE.
Observed Result
Plasmashell freezes. After attaching gdb, retrieving the stack trace, and
continuing gdb, the notifications from KDE Connect appear all at once.
Expected Result
Plasmashell should not freeze.

Additional Information
I wasn’t able to capture a backtrace for kdeconnectd and couldn’t easily
reproduce the freeze. Routine notifications, like file downloads, are not
transferred through KDE Connect, and messaging notifications didn’t trigger the
bug. The OrgKdeKdeconnectDeviceNotificationsNotificationInterface resides in
generated code, and I didn’t attempt to compile KDE Connect or inspect its
files for debugging.
