System Information
Operating system and graphics card
OS X 10.7.5 ATI Radeon HD 2600 XT 256 MB
Blender Version
Broken: 2.69.0 r60991, also builds hash d71bcab, 6734936

Short description of error

Attempting to convert multilayer .exr to png using file output node in compositor, only outputs first frame of sequence
FYI my .exr was only one layer
uploading 3 frames as example <sorry couldn't upload directly as files too large-let me know if you need .exr files to test>

Exact steps for others to reproduce the error

Load .exr image sequence into file input node,
adjust file output node paths as needed
render animation
only one frame is output.

Let me know if you need the .blend set up with a relative path layout. Thanks.

I'm downloading yesterday's later build to try, in case this is fixed by https://developer.blender.org/T38074

I'm not actually sure what does it mean "only one frame is the output"?

From my tests exr sequence has been converted to pngs just fine. Could help if you scale exrs down and setup .blend file with relative path which fails to work for you.

I couldn't redo this problem either but I had to change the paths, after that it outputs all frames.

I'm not sure how it could output only one frame. If it can't write to the given location, then it gives an error and animation rendering is stopped, so I guess in that case it's true that the File Output node would write one frame, then the render output tries to write and fails, and it stops.

But further, we really need more information, so far no reply in 2 weeks so will close until we get more information to investigate this.
