great , unfortunately this patch can't be applied against  1.5.1, or ?
At least at  an stable hardened Gentoo I do get :

Try adding an include for QStringLiteral perhaps :). I pushed this to the 1.6 branch (and master) which is Qt 5.

Qt4 have no QStringLiteral.
To compile with Qt4, replace QStringLiteral by QLatin1String.

yep, that was it  - thx guys,
