Passing in a Readable stream to gifify does not work in node

[lobabob]

If I do

outputFileStream = fs.createWriteStream('out.gif');
gifify('blah.gif', { ... }).pipe(outputFileStream);

it works, but if I do

inputFileStream = fs.createReadStream('blah.gif');
outputFileStream = fs.createWriteStream('out.gif');
gifify(inputFileStream, { ... }).pipe(outputFileStream);

it fails with the following

Error: Uncaught, unspecified "error" event. (convert: no decode delegate for this image format `' @ error/constitute.c/ReadImage/501.
convert: no images defined `gif:-' @ error/convert.c/ConvertImageCommand/3210.
