(Another) segmentation fault

[Lebowski]

I am using that.

void GlavnoO::test_clicked()
{
    bool ok = FALSE;
    QSqlDatabase *baza = QSqlDatabase::database();
    if (baza) {
	ok = baza->isOpen();
    };

void GlavnoO::test_clicked()
{
    bool ok = FALSE;
    QSqlDatabase *baza = QSqlDatabase::database();
    if (baza) {
	ok = baza->isOpen();
    };

To copy to clipboard, switch view to plain text mode 

Originally it was without 'if (baza) ...' statement.
