When doing something like this:
class A {
A();
QString a;
};
A::A():a(0) {
}
The error message is
test.cpp: In constructor ScribusDoc::ScribusDoc():
test.cpp:6:12: error: call of overloaded QString(int) is ambiguous
/usr/lib64/qt4/include/QtCore/qstring.h:427:43: note: candidates are:
QString::QString(const QByteArray&)
/usr/lib64/qt4/include/QtCore/qstring.h:425:43: note:
QString::QString(const char*)
/usr/lib64/qt4/include/QtCore/qstring.h:726:8: note:

/usr/lib64/qt4/include/QtCore/qstring.h:106:5: note:
QString::QString(QChar)
/usr/lib64/qt4/include/QtCore/qstring.h:105:14: note:
QString::QString(const QChar*)
It would be useful if there was an indication of which initializer is being
processed at the time, e.g.
test.cpp: In constructor ScribusDoc::ScribusDoc():
test.cpp:6:12: error: call of overloaded QString(int) is ambiguous while
initializing member a'
/usr/lib64/qt4/include/QtCore/qstring.h:427:43: note: candidates are:
QString::QString(const QByteArray&)
/usr/lib64/qt4/include/QtCore/qstring.h:425:43: note:

/usr/lib64/qt4/include/QtCore/qstring.h:105:14: note:

especially if the class initializes tens of variables rather than just one.
