Description Edward Nygma 2018-02-01 18:17:34 UTC

Application: plasmashell (5.11.4)

Qt Version: 5.9.2
Frameworks Version: 5.41.0
Operating System: Linux 4.14.13-300.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

-- Information about the crash:
I have just closed Google Chrome and, while the window disappeared, the task bar still displayed the Chrome entry. Hovering it (trying to click on it), made plasma crash and restart itself.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Marco Martin 2018-02-02 10:41:12 UTC

even tough symbols aren't completed, it can be deduced that on plasma side the crash is at iconitem.cpp line 233
if (width() > 0 && height() > 0) {
        schedulePixmapUpdate();
    }
(which in turn calls polish()

which I don't understand much why it crashes, i would guess that item is in tearing down process but hasn't been deleted yet

Comment 2 Marco Martin 2018-02-02 10:42:45 UTC

from the implementation of QQuickITem::polish()

maybe d->window is a dangling pointer?

void QQuickItem::polish()
{
    Q_D(QQuickItem);
    if (!d->polishScheduled) {
        d->polishScheduled = true;
        if (d->window) {
            QQuickWindowPrivate *p = QQuickWindowPrivate::get(d->window);
            bool maybeupdate = p->itemsToPolish.isEmpty();
            p->itemsToPolish.append(this);
            if (maybeupdate) d->window->maybeUpdate();
        }
    }
}

Comment 3 Marco Martin 2018-02-02 10:43:05 UTC

Can you try to reproduce with qtQuick debug symbols installed?

Comment 4 Edward Nygma 2018-02-05 22:16:44 UTC

Sorry, but I can't really reproduce it by just starting and closing Chrome. Most likely there were other factors involved that I did not notice to record.
