[vtkusers] X Error: BadWindow, vtk5.8.0, Qt4.6.2

[John Platt]

Hi All,

My mistake. The QVTKWidget was being used as a parent to another widget 
hosted by the QDockWidget. Clint's debugging help was spot on. You can 
specify qt_x_errhandler as the function to break in.

Thanks for the help.

John.
