Description Norbert Preining 2021-01-14 02:12:08 UTC

SUMMARY

Selecting the "Mobile broadband" entry in the settings application, or
starting it directly with
   systemsettings5 mobilebroadbandsettings
results in 100% CPU on one core, and no output/display is generated.

STEPS TO REPRODUCE
1. systemsettings5 mobilebroadbandsettings

OBSERVED RESULT
The same set of error messages is shown repeatedly (until interrupted):

file:///usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/kirigami.2/PageRow.qml:591:5: QML ColumnView: possible QQuickItem::polish() loop
file:///usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/kirigami.2/PageRow.qml:591:5: QML ColumnView: ColumnView called polish() inside updatePolish() of ColumnView

Nothing is displayed

EXPECTED RESULT

Display of mobile settings, or a warning that this is not supported on the current device.

SOFTWARE/OS VERSIONS

KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.78.0
Qt Version: 5.15.2

Comment 1 Norbert Preining 2021-01-14 02:15:37 UTC

I forgot to mention (but this is somehow implied), that plasma-nm was compiled with -DBUILD_MOBILE=true

Comment 2 Nicolas Fella 2021-01-14 14:38:13 UTC

The Mobile Broadband KCM has been removed in https://invent.kde.org/plasma/plasma-nm/-/commit/177a2641a0f9655d26042ed1c38865aea048ce94
