Runtime crash with Table

Hi,

Well, I try to display a part of my SQL Database on a QTableView, simple right ?
Well the problem is the code compiles silently but whenever the signal that should initiate the QTableView is "launched/activated", the app crashes...
When looking at the crash log I finally found that there was a "Bad access error":
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000008
Exception Note: EXC_CORPSE_NOTIFY

Here is the code :

Code:

---

void MainWindow::printTableView()
{
    QSqlDatabase db = connectionArticle->getDB();  //Here I retrieve the database connection from an other window
    QSqlQuery *query = new QSqlQuery();
    if (db.open()){
    if (db.databaseName()=="article")
    {
    query->prepare("SELECT name,type FROM article");
    }else{
    query->prepare("SELECT name,isWorking,currentArticle FROM journalist");
    }
    query->exec();
    model->setQuery(*query); // When using the debugger, I never pass through this line (it stays here for ever)
    }
 
ui->tableView->setModel(model);

Well, if anyone knows where I missed I would be glad to know 1
Thank you in advance !

Added after 6 minutes:

Well I figured the little error in the query declaration...

Code:

---

QSqlQuery *query = new QSqlQuery(db);

But it changes nothing to the problem...

Where did you initialize the model?
