[vtkusers] QT 4.7.4 + VTK 5.10.1 + OSX rendering crash

[Alessandro]

Hello,

I'm working on a multi-platform project using QT, VTK and ITK. I'm working on a team so we run the project on several environments. Now, I'm currently stuck on an OSX issue. Using a Linux environment, provinding QT 4.8.3 and VTK 5.10.1 everything is ok. Once I try to run the same code on a OSX 10.6.8, QT 4.7.4 and VTK 5.10.1, the program crash in the paintEvent/rendering process with this error stack:
