I have take a look to this and it seems that there´s a segfault when running a
ProgressBar with undefined duration under opengl graphics system

According to gdb output, seems like a qt bug :/. I will try to find a
workaround to this but we probably have to loose magnifier for ssu. 

Crazy idea here. Will be possible to binary patch qt to fix this and the
SipAttributes problem?
Comment 2 Carlos Martín 2012-04-08 15:00:52 UTC
This is a problem associated to Qt 4.7.0. A workaround is to set qt
graphicssystem to something different to opengl (raster, for example). I've
updated examples to reflect the circumstances.
