Qt example "Font sampler" Seg fault problem.

[pogusm]

Please See this link. ( http://www.youtube.com/watch?v=YYxLRrz69KU )

It's Qt example "Font sampler".

1. Select some fonts.
2. Run Print Preview. (several pages)
3. Change Portrait to Landscape. Then, Seg fault.

Is this bug isn't it?

I do not know how to fix.

Help me please.

Thank you.
