Comment 5 Nicolas Fella 2024-06-02 13:32:23 UTC 
This is caused by the call to QApplication::processEvents in https://invent.kde.org/plasma/plasma-nm/-/blob/master/vpn/l2tp/l2tpipsecwidget.cpp#L324

It causes the WA_DeleteOnClose for ConnectionEditorDialog to be executed too early while settings are still read

Git commit 59de1353dc09190a71caede6107734a5717205ab by Nicolas Fella.

Don't call QApplication::processEvents to update size hint

The current code calls setSizePolicy and then resizes the dialog to the sizeHint.

However sizeHint is only updated asynchronously, so we use QApplication::processEvents
to force that.

Processing the events this way can cause unforseen havoc, in particular it causes dialogs
that use WA_DeleteOnClose to be closed too early, causing crashes.

Instead of force processing the events delay the setting of the new size one event loop iteration
