Erk. Seems to happen only within the newly attached blend.

Hi,

I can't reproduce this from an default file, or any other combination, the only way I got a crash is using the test_dof(1).blend.

The backtrace don't help, because I do different things here, remove the nodes and the image, save with another filename, open again and still have the same problem if I use the blend file and the crash happen in different part of the code.

Can you remember how you create this file ? was with an older version of blender, right ?

BTW I create two exr with blender, one as rgb and another as rgba and both work fine.

Thanks,

- Diego

It was a blend file created with a relatively recent SVN from a friend, so I am unable to recreate it.

It is clearly doing some bad mojo however.

this is a simple NULL check, though I'm not sure if it should just be checked and ignored or investigated further, will leave for now.
