Summary

0001771: Segfault in keyframeedit.cpp when working on the timeline

Description

On the last line here:
void KeyframeEdit::slotAdjustKeyframeInfo(bool seek)
{
    QTableWidgetItem *item = keyframe_list->currentItem();
    if (!item)
        return;
    int min = m_min;
    int max = m_max;
    QTableWidgetItem *above = keyframe_list->item(item->row() - 1, item->column());
    QTableWidgetItem *below = keyframe_list->item(item->row() + 1, item->column());
    if (above)
        min = getPos(above->row()) + 1;
    if (below)
        max = getPos(below->row()) - 1;

    keyframe_pos->blockSignals(true);
    keyframe_pos->setRange(min, max);
    keyframe_pos->setValue(getPos(item->row()));
    keyframe_pos->blockSignals(false);
    for (int col = 0; col < keyframe_list->columnCount(); col++) {
        DoubleParameterWidget *doubleparam = static_cast <DoubleParameterWidget*>(m_slidersLayout->itemAtPosition(col, 0)->widget());
        if (!doubleparam)
            continue;
        doubleparam->blockSignals(true);
        doubleparam->setValue(keyframe_list->item(item->row(), col)->text().toInt());

Segfaults in Effect Stack list

Notes
(0005662) Granjow (developer) 2010-08-24 19:32	Is it possible that item has been deleted in the meantime, by another thread?

(0005663) Granjow (developer) 2010-08-24 20:27	Ah. -DCMAKE_BUILD_TYPE=debug. I've just been clicking through clips in the timeline, each of them with a SOP/Sat effect. this is 0x0 in qtablewidget.h: inline QString text() const { return data(Qt::DisplayRole).toString(); }

(0005664) Granjow (developer) 2010-08-24 20:32	Fixed in r4753 http://kdenlive.svn.sourceforge.net/viewvc/kdenlive/trunk/kdenlive/src/keyframeedit.cpp?r1=4753&r2=4752&pathrev=4753 [^]
