           Summary: wish: use empty strings if values are unknown instead of
                    "-1"
           Product: kalzium
           Version: 1.3.1
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kalzium kde org
        ReportedBy: franke.daniel gmail com


Version:           1.3.1 (using KDE 3.4.2, Gentoo)
Compiler:          gcc version 3.3.5-20050130 (Gentoo 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1)
OS:                Linux (i686) release 2.6.11.11

Please replace any occurence of "-1" where it means "unknown value" or "not applicable" by an empty string (or its textual expression, e.g. "unknown" =). 

"-1" might be a sensible value at some point and may be confusing otherwise, at least at first sight. For example: "ElectroNEGATIVITY" of Helium: "-1" -- hu?

Thanks!
