Bug ID: 518361
Summary: Plasmoid FullRepresentation.qml: TypeError in
getPlanStatus() when DataSource not yet loaded
Classification: Applications
Product: kup
Version First 0.10.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
The Kup plasmoid's FullRepresentation.qml throws multiple TypeErrors on every
session startup because getPlanStatus() lacks
a null/undefined check. The backupPlans DataSource has not yet loaded plan
data when the QML delegate tries to access it,
causing backupPlans.data["plan 0"] to be undefined.
This can prevent the plasmoid from correctly initializing and may interfere
with scheduled backup triggering.
Steps to reproduce:
1. Configure a Kup backup plan with an external drive as destination
2. Log in to a Plasma 6 session with the Kup applet in the system tray
3. Observe journal output: journalctl --user -t plasmashell
Expected behavior:
No errors; the plasmoid gracefully handles the DataSource not being ready
yet.
Actual behavior:
Multiple TypeErrors at FullRepresentation.qml:137:
TypeError: Cannot read property 'description' of undefined
TypeError: Cannot read property 'status heading' of undefined
TypeError: Cannot read property 'status details' of undefined
TypeError: Cannot read property 'icon name' of undefined
TypeError: Cannot read property 'destination available' of undefined
TypeError: Cannot read property 'bup type' of undefined
TypeError: Cannot read property 'log file exists' of undefined
Root cause:
In plasmoid-qt6/contents/ui/FullRepresentation.qml, line 136-138:
function getPlanStatus(planNumber, key){
return backupPlans.data["plan " + planNumber.toString()][key];
}
backupPlans.data["plan 0"] is undefined when the Plasma5Support DataSource
hasn't connected yet. By contrast,
getCommonStatus() in main.qml already handles this correctly with a fallback
check.
Suggested fix:
Add null-safety to getPlanStatus(), matching the pattern used in
getCommonStatus():
function getPlanStatus(planNumber, key){
var plan = backupPlans.data["plan " + planNumber.toString()];
if(plan === undefined) return "";
return plan[key];
}
The same issue also exists in
plasmoid-qt5/contents/ui/FullRepresentation.qml.
Environment:
- Kup 0.10.0
- KDE Plasma 6.5.2
- Qt 6.9.2
- KDE Frameworks 5.116.0
- Linux (TUXEDO OS 24.04 / Ubuntu Noble base)
