[Interest] Annoying Bug - Qt 4.8.1 bug?

[Björn Piltz]

I encountered a similar problem with similar code. My problem was the
following unexpected feature of QProgressDialog::setValue():

> Warning: If the progress dialog is modal (see QProgressDialog::QProgressDialog()),
setValue() callsQApplication::processEvents(), so take care that this does
not cause undesirable re-entrancy in your code. For example, don't use a
QProgressDialog inside a paintEvent()!

In my case this lead to a stack overflow because setValue() was called
recursively. This might be your problem as well.
