Bug ID: 431508
Summary: Crash in kglobalaccel setting
Product: systemsettings
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_keys
Assignee: k...@michael-jansen.biz
Reporter: k...@davidedmundson.co.uk
CC: plasma-b...@kde.org
Target Milestone: ---
Split from https://bugs.kde.org/show_bug.cgi?id=426047 # 26
- What I was doing when the application crashed:
Configuring global shotcuts
- Unusual behavior I noticed:
I saved the shortcuts with apply button but they didn't actually works, also
all shorcuts are unconfigured, I can't do an Alt + Tab
- Custom settings of the application:

-----
Reading the code it's clear what's wrong
connect(infoWatcher, &QDBusPendingCallWatcher::finished, this, [=] {
A reply can be valid but empty. At which point calling
info[0].componentUniqueName();
obviously crashes.
I don't know if it's safe to just guard in the lambda.
