Problem adding items with icons to a non-visible QListWidget

Hi,

I have a simple application with two tabs. In one of the tabs I have
a QListWidget.

If I add several QListWidgetItems to the list all with different icons, the
icons are not displayed correctly (shown with noise) if the tab that
contains the list is not selected when the addItem() method is called.

Is this a bug?

Nevermind, I was not creating the icons correctly.
