pdftohtml dependance

[Rakotomandimby Mihamina <mihamina.rakotomandimby@etu.univ-orleans.fr>]

Hi,
I am using Sid, with some pieces of experimental.
I try to install a package:

  mihadev:~# apt-get install pdftohtml
  [...]
  The following packages have unmet dependencies:
    pdftohtml: Depends: poppler-utils (>= 0.4.5-1)
  E: Broken packages
  mihadev:~# dpkg -l poppler-utils
  [...]
  ii  poppler-utils                0.5.4-2 

What's wrong?
Thank you.
