But the source model explicitly avoids adding items for the default styles, so these calls will return an invalid index, which results in a -1 being added as a row to m_usedStyles. In the next call to styleApplied, this will result in an invalid internalId being used to try to get the corresponding style from the style manager. The invalid style pointer is then used, resulting in the crash described in the bug.
