Valgrind - libgtk-x11

I correct my all memory leak in my program writing in Qt.
I found some errors which can not cope.

==3343== Conditional jump or move depends on uninitialised value(s)
==3343==    at 0x80B4320: g_utf8_offset_to_pointer (in /lib/x86_64-linux-gnu/libglib-2.0.so.0.4002.0)

my main function

#include "mainwindow.hh"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec(); //this is my 9th line
}

The whole day trying to fix it and I don't have any idea what's mean.
Could someone help me?

For libraries which you're not interested in and have no means to fix problems, you create valgrind suppression file and they won't be shown again

Please see manual

http://valgrind.org/docs/manual/manual-core.html

Section 2.5 Suppressing errors
