This performs a recursive search, which is slow and potentially wrong.

You didn't read the KGlobal documentation carefully enough :-)

     * @deprecated since Qt 5, use QObject::findChild(FindDirectChildrenOnly)

-> you need to pass the FindDirectChildrenOnly flag.
This flag only exists in Qt5 though, so you need to either wait for the Qt4 
support to be dropped (the current plan is to do that in 2 weeks), or to use 
#if QT_VERSION >= QT_VERSION_CHECK(5, 0, 0)
qt5 code
#else
qt4 code
#endif

Thanks.
