The one the (tested, working) solution of which is the following:

(lyx_sty.C)

string const boxwidth_def =
    "\\newlength\\w\n";

string const fboxwidth_def =
    "\\newcommand\\setfboxwidth[0]{%\n"
    "\\setlength\\w{\\columnwidth}\n"
    "\\addtolength\\w{-2\\fboxsep}\n"
    "\\addtolength\\w{-2\\fboxrule}}%\n";

string const ovalboxwidth_def =
    "\\newcommand\\setovalboxwidth[0]{%\n"
    "\\setlength\\w{\\columnwidth}\n"
    "\\addtolength\\w{-2\\fboxsep}\n"
    "\\addtolength\\w{-0.8pt}}\n"; // 2x \thinlines width

and (insetbox.C):

    if (pt == "Boxed") {
        os << "%\n\\par\\setfboxwidth\\fbox{\\parbox{\\w}{%\n";
    } else
        os << "%\n\\par\\setovalboxwidth\\ovalbox{\\parbox{\\w}{%\n";

...

void InsetBox::validate(LaTeXFeatures & features) const
{
    features.require("boxwidth");
    if (params_.type == "Boxed") {
        features.require("fboxwidth");
    } else {
        features.require("fancybox");
        features.require("ovalboxwidth");
    }
    inset.validate(features);
}
