I have a simple but wierd problem.

this is my simple program:

require 'RMagick'
img = Magick::ImageList.new("dsc01748.jpg")

dsc01748.jpg is an image in the current path.
After running it, this is the error:

#ruby ./test.rb 
/usr/lib/ruby/1.8/RMagick.rb:1377:in `read': unable to open image `1748.jpg': No such file or directory:  (Magick::ImageMagickError)
        from /usr/lib/ruby/1.8/RMagick.rb:1377:in `initialize'
        from /usr/lib/ruby/1.8/RMagick.rb:1376:in `each'
        from /usr/lib/ruby/1.8/RMagick.rb:1376:in `initialize'
        from ./test.rb:3:in `new'
        from ./test.rb:3

This used to work just fine, I also tested an older version of rmagick.
Is there something changed in ruby?

I can't figure it out, what am I missing?
