[Qt-interest] segmentation fault confusion

[Avishek_Sharma]

Hi everyone,
   am working on a photo gallery which was designed using Qt 3.3.

All that I changed in the layout(which I did using designer) was add a Label 'rotatepic' near the 'Rotate' button.

In the slot rotate() for the 'Rotate' button,I added one extra line-
rotatepic->setPaletteBackgroundColor(QColor(170,255,0));

so that when I click the 'Rotate 'button,the 'rotate' label next to it also changes to the same colour as the 'Rotate' button changes to.But,when I run the program,I get a segmentation fault when I click the 'Rotate' button.

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
