[Paraview] ParaView Web - module twisted.internet error

[Sebastien Jourdain]

Hum, that is weird.

It could be a bug.

Do you mind doing a diff between the 2 python modules between 5.2 and 5.3.

Twisted should be the same. Then on the ParaView side, I'm not expecting
much difference.

Thanks for tracking that down...
