I'm convinced now that this is wrong. And I just don't understand
this crash. Why does this call:
QModelIndexList indices = tocTV->model()->match(
tocTV->model()->index(0, 0),
Qt::DisplayRole, "*", -1,
Qt::MatchFlags(Qt::MatchWildcard|Qt::MatchRecursive));
lead to a segfault?
Maybe tocTV->model() is equal to zero?
It is zero.
I'm also seeing "type not found" errors printed to the screen, from
lines 267 and 371 in TocModel.cpp, just before the crash.
So, if I add "if (!tocTV->model()) return;" to the beginning of
TocWidget::filterContents(), then that crash goes away. Then I see the
"type note found" errors constantly.
And with that crash gone, I get a different one, which looks similar to
the one in branch. See line 37, etc, below. The currentIndexChanged
signal is again the problem, but this time because it tries to reset the
focus to the main work area, and we are not ready to do that yet.
So that's really the cause of all of this, it seems to me: Qt 4.6.x is
emitting that signal when we reset the model for the combo box. Perhaps
we could disable signals for that box, but I guess that probably hides
the real bug.
I wonder if the real problem is that we are entering updateBuffer (the
old updateLabels) before we really should.
