I've identified the bug. It's just that sscanf uses the current locale 
definition of "decimal_point" to extract a float from the string "0.9300".
For some locales the decimal point is just that, a point, but for
others (for example for german, french, or spanish) it is a comma,
so the sscanf will extract "0" instead of "0.93"

The suggested patch is:

*** dpkg-1.4.0.19/dpkg-deb/main.c.orig Fri Aug 22 18:11:40 1997
--- dpkg-1.4.0.19/dpkg-deb/main.c      Fri Aug 22 18:12:03 1997

    jmp_buf ejbuf;
  
    setlocale(LC_ALL, "");
+   setlocale(LC_NUMERIC, "POSIX");
    bindtextdomain(PACKAGE, LOCALEDIR);
    textdomain(PACKAGE);
