I have problems with QstringList during make, this is
what it looks like:

void Kapp::selectFile()
        {
        QStringList chosen =
QFileDialog::getOpenFileNames ();
 if (chosen != "") { // returned string is empty, if
user pressed "cancel"
 kLineEdit1->setText (chosen);
 }
        }

it works ok though when I take out the last 3 lines:

"if (chosen != "") { // returned string is empty, if
user pressed "cancel"
 kLineEdit1->setText (chosen);
 }"

and this is the error I get:
