This is due to the definition of QT_NO_CAST_FROM_ASCII in the qtcreator.pri.
See: 
http://qt-project.org/doc/qt-5.0/qtcore/qstring.html#QT_NO_CAST_FROM_ASCII

For non-translatable strings use QLatin1String("...").
Use tr("...") for translatable strings.


BR,

Joerg

P.S. It's possible to remove that define from your plugin but that's 
considered bad style.
