QInputDialog::getText - can't get access by keyboard

[m_fighter]

System: gentoo. Qt 4.6.2. Not using any display manager - just X server.

I try to get user input, but dialog doesn't react on keyboard, even can't close it by pressing Esc or Enter - only by mouse clicks.

Code:

bool ok;
    QString pwd = QInputDialog::getText(this, NULL, tr("Password:"), QLineEdit::Password, "", &ok);
    if( ok && !pwd.isEmpty() )
    {
		...
    }

bool ok;
    QString pwd = QInputDialog::getText(this, NULL, tr("Password:"), QLineEdit::Password, "", &ok);
    if( ok && !pwd.isEmpty() )
    {
		...
    }

To copy to clipboard, switch view to plain text mode 

QApplication::focusWidget() remains parent of QInputDialog (guess it by logging) - is it common behavior?
