[Paraview] Crash when using the Information Tab in Object Inspector

[Utkarsh Ayachit]

Paul,

I've committed a fix and it will be included in 3.12. Thanks for reporting.

FYI,

commit 6ffd41964cd9681af26769e8e6cf7778de7515ae

    Fixed BUG #12571.  Update event wasn't fired when needed.

    vtkSMSourceProxy was not firing UpdateEvent when UpdatePipeline(time) was
    called. The data info was updated correctly however. So the Information tab
    ended up holding references to obsolete information instances. Fixed that.
