[Paraview] memory leak in writer

[Natalie Happenhofer]

I have written it months ago and it worked well for small files and timeseries for about 30 files - I have just come across it trying to write a time series of 200 files. 

I can already download ParaView 3.6? Great, I did not know this!

thx,
Natalie
