[vtkusers] Cocoa error using VTK from Python on OS X

[Arve Knudsen]

I'm developing a scientific visualization framework in Python, called
Viper (http://www.fenics.org/wiki/Viper), which is based on VTK. On OS
X (10.5) I am running into certain errors, which seem to be caused by
VTK. In one of the Viper demos, an error is reported after returning
from vtkRenderWindowInteractor.Start for the first time and another
('[...] vtkCocoaServer autoreleased with no pool in place[...]') after
calling it for the second time. After the last error the application
just hangs. Could someone be so kind as to run the Viper demo in
question (get Viper from
http://conduit.simula.no/files/Viper.tar.bz2), trigger the error by
pressing 'q', and try to determine the eventual VTK bug?

Thanks,
Arve
