--- Comment #5 from Lamarque V. Souza <lamar...@kde.org> ---
The commit 10d8d20a3bc4016ee271aee234f7727e5640cedc causes a crash in
SensorDataModel::onMetaDataChanged during this call
beginInsertColumns(QModelIndex{}, column, column);
column is calculated using
auto column = d->sensors.indexOf(sensorId);
but since your commit removed this code
for (const auto& sensor : sensors) {
sensorInfos[sensor] = KSysGuard::SensorInfo();
}
the size of sensors and sensorInfos are not in sync for certain amount of time.
This is backtrace:
[08:07:24.435] unknown: ASSERT: "first <= columnCount(parent)" in file
