Short description: Memory leakage in QWebView

Did:

We are using the QWebView widget to display status about our system. The widget
is therefore updated very often by altering a html-text and then update the
display using the SetHtml-function (we have also tried the setContent).

The problem is that there seems to be a memory leakage. The memory usage for
the exe-process continues to grow as we update the widget content. It does not
help to delete the widget, we have to kill the exe-process to retrieve the
memory back to the PC.

The memory usage does not grow if we skip to update the widget so the leakage
seems to be within the widget.

Expected to see:

Stable memory usage

Got instead:

Increasing memory usage
