See #242696 for a better stack trace.

Tony, this bug might be introduces with your "recent" changes? Haven't you changed something with stacked layouts?

Comment 7 Tony Murray 2010-07-03 16:55:39 UTC 
Urs, I can't see how this is crashing, unless there is a bug in Qt 4.6.2.   All we are doing is calling KTabWidget::addTab(page, label).

KRDC 4.4 does not use QStackedLayouts, just KTabWidget.  The underlying implementation in Qt for QTabWidget uses them of course.
Comment 8 Urs Wolfer 2010-10-24 20:49:07 UTC 
Can you reproduce this crash with KRDC from KDE SC 4.5?
