QStandardItemModel itemChanged signal not always firing

[Dolphin]

I have QStandardItemModel displayed in a QTreeView. When user clicks on certain items in the view they become editable. After the user has changed a value I should always hit my breakpoint in on_dataChanged (i.e. the slot) but I do not always (if I save the data is not updated to file even though it is updated on screen). When I do hit the breakpoint at the start of on_dataChanged the data is saved to file and updated on screen correctly.

• I always hit the slot the first time I edit some data after loading the app but not necessaries the first time I edit each item.
