Comment 1 Laurent Montel 2012-01-12 18:30:51 UTC 
Can't reproduce it. 
But code is:
void AclEntryDialog::setPermissions( KIMAP::Acl::Rights permissions )
{
  QAbstractButton* button = d->mButtonGroup->button( KIMAP::Acl::normalizedRights( permissions ) );
  if ( button ) {
    button->setChecked( true );
  } else {
    QRadioButton *radioButton = new QRadioButton( AclUtils::permissionsToUserString( permissions ) );
    d->mButtonLayout->addWidget( radioButton );
    d->mButtonGroup->addButton( radioButton, permissions );
  }

  d->mCustomPermissions = permissions;
}

I don't understand why it crashs because we add just an radiobutton
Comment 2 Laurent Montel 2012-01-12 18:33:01 UTC 
ok found: mButtonLayout is never defined. => it will crash normal
d->mButtonLayout->addWidget( radioButton );
