In windows, without temp path set, the 'save buffers' render option crashes. I've coded a blenlib BLI_is_writable(char *filename) to check for such cases. This is not much needed in Blender, since the open() command is checked for. However, file saving happens deep inside the C++ exr lib, and it throws an exception crash when a file cannot be written.
