A Texture Input into the Blur Node (Value to Size) crashes Blender while rendering.
It doesnt depend on wether its a generated texture or image.

See attached file.

I can reproduce this bug too.
Here is a GDB trace log : http://www.pasteall.org/17439

Last SVN (r.33541), Ubuntu 10.10 x32-64, GTX 275.

Thank you for the report Christian.

Ton, you made some changes in texture/composite recently.
the buffer is NULL, so simple to check but not sure how this is supposed to work.

Texture is a procedural buffer-less node. Before it didn't work either, it just gave black.
Will check on it.

Fix went to svn.

Note: the texture node is procedural, it has no buffer or size really, works resolution independent. Input in blur node will give no result, like RGB color node.

I found time to fix this today, not in 2.56a release, but if you can build yourself you can get texture nodes work as you want it!
From the svn log:

Compositor: Texture Node now behaves like an image.
- Image always in render output size
- Buffer outputs RGBA and Value both supported
- Works for filter and blur and scaling too.
- Mixing 2 textures works
