[vtkusers] Program crash with vtkPolyDataConnectivityFilter + vtkActor

[Leonardo Florez]

Hi everybody,

(at the end of this message is the "problematic" code segment)
I'm using a vtkPolyDataConnectivityFilter with a pipeline connection to
a vtkActor in a TCL/TK8.3 application. When it starts and executes this
code for the first time, no error occurs. But when the application has
to execute this code again, in the same application process (I mean,
without closing the application), it crashes the application after
execution of "catch {connActor Delete}" command and finish the
application. I don't know what happens, could anybody help me?, or is
this a vtk's bug?

Thanks,
LFV
