Page range not imported correctly from BibTex

Importing the following BibTex file:
@article{Apostolakis:bk0088,
author = "Apostolakis, Joannis and Hofmann, Detlef Walter Maria and Lengauer, Thomas",
title = "{Derivation of a scoring function for crystal structure prediction}",
journal = "Acta Crystallographica Section A",
year = "2001",
volume = "57",
number = "4",
pages = "442--450",
month = "Jul",
doi = {10.1107/S0108767301004810},
url = {http://dx.doi.org/10.1107/S0108767301004810},
}

created inside Zotero a record with: "Pages: 442450"
without any separator.

The "--" idiom is absolutely standard in BibTex.
I'm using Zotero 1.0.3
