Bug ID: 402439
Summary: Model error with Kickoff RunnerModel
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Application Launcher (Kickoff)
Assignee: k...@davidedmundson.co.uk
Reporter: k...@davidedmundson.co.uk
CC: plasma-b...@kde.org
Target Milestone: 1.0
In an attempt to check there's no bug our side with the common plasma crash in
kickoff I attached QAbstractItemModelTester to our model.
Unpredictably (one in every few launches) I do get a model error:
