Large blurred objects don't export

Bug Description

A poster I am making has a very large circle that has a 50% blur. I found that I could not go above 25% blur and still have the blurred object render on export. Attached is a sample of a 5000 * 5000px black square over a yellow square. Try blurring the black square by 100% and exporting the yellow square at 300dpi. The resulting export.png will just be the yellow square.

confirmed in svn, blur that large requires a pixel buffer of almost 3 gb, allocating it fails

Changed in inkscape:
status: New → Confirmed

Just to make sure, the image does export. The yellow square from the example is exported, but the blurred black square is gone. I suppose like you say, the allocation fails, but then Inkscape just silently moves on.

I can export so the black square is visible. I have 32GB of memory, so that might explain it. It took several minutes.
