That's how I would do it too, but with some batteling,
I use this (even though my problem was a bit more about
escaped \s that escape \"s):
    index = 0;
    while (true) {
        index = msgid.find("\\\"", index);
        if (index == -1)
            break;
        if (index > 1 && msgid.at(index - 1) == '\\' && msgid.at(index -
2) != '\\')
            msgid.replace(index - 1, 3, "\\\"");
        else
            msgid.replace(index, 2, "\"");
    }

I think, \\\" is the way you write it for QString and QRegExp expects
each \ to be escaped once more, so you end up with 
\\\\\\",
