(Updated Dec. 30, 2013, 3:55 p.m.)
Review request for Kate and Milian Wolff.
Changes
-------
Addressed Milian's suggestions.
Summary (updated)

Fix assert in ~QPersistentModelIndex
Bugs: 236948

Description (updated)
-------
Fix assert in ~QPersistentModelIndex
KateCompletionWidget may call QAIM::setCurrentIndex during a reset of
the model, inside KateCompletionWidget::modelContentChanged(). At this
point, model indices are invalid, but QAIM wasn't informed about it.
The main problem is that KateCompletionModel doesn't use the
(relatively) new {begin,end}ResetModel blocks to make persistent model
indices
invalid as soon as we start resetting the model. Instead reset() is used
*after* we have reset the model. However, KateCompletionModel may emit
contentGeometryChanged too early (before a reset()) and hence triggering
QAIM::setCurrentIndex while QAIM is still referencing now invalid
persistent model indices.
Other changes:
Remove contentGeometryChanged. Instead, use layoutChanged() and
modelReset() signals to react to model changes.
This also ports KateCompletionModel away from deprecated QAIM methods
such as QAIM::reset()
BUG: 236948
FIXED-IN: 4.13
