[Qt-interest] segmentation fault confusion

[Malyushytsky, Alex]

Check the value of "rotatepic".
It was probably not initialized properly, so it is either nill or garbage.

Even though this is not a QT problem, I would recommend search for "Debugging Techniques" in the QT documentation ( qDebug, Q_ASSERT, Q_CHECK_PTR(ptr), etc).

In the slot rotate() for the 'Rotate' button,I added one extra line-
rotatepic->setPaletteBackgroundColor(QColor(170,255,0));
......
If I comment out the line rotatepic->setPaletteBack....., The 'Rotate' feature works fine.

I can't figure out what's wrong.
Please advice.

Thanks in advance.
Avi
