Qt5 QHash pretty printer not working

As shown in the attached image, the Qt Visual Studio plugin doesn't properly print a QHash:

    QHash<QString, QVector<double> > complexData;
    complexData["foo"] = QVector<double>() << 1 << 2 << 3 << 4 << 5;

it seems to work for a plain QString, so I'm unsure what's going wrong here. this used to work in older versions of the plugin I believe

if it matters: note that I don't have a full VS project up and running, instead i just ran

devenv /debugexe somebinary.exe
