[Paraview] unregister timer errors

[David Doria]

When I click the "Split Horizontal" button and then click "Spreadsheet
View", I get:

"Application asked to unregister timer 0x7800000e which is not
registered in this thread. Fix application."

in the "Output Messages". Everything seems to continue working
properly once I "Close" the Output Messages.

Any idea why this would happen? It does not happen with all views,
only the spreadsheet.

Thanks,

David
