RMagick question

I'm trying to convert several (300) .tif files to .gif files using
RMagick.

But I'm getting the following message:

irb(main):030:0> i = Image::read("ir_mmw_000.tif").first
=> ir_mmw_000.tif TIFF 640x480 PseudoClass 256c 8-bit 311238b
irb(main):031:0> i.class
=> Magick::Image
irb(main):032:0> i.write "foo.gif"
Magick::ImageMagickError: pixel cache is not open `foo.gif':
from (irb):32:in `write'
from (irb):32
from :0

Any ideas?

Phil
