--- Comment #3 from Adriaan de Groot <adridg at freebsd.org> ---
I get a fairly consistent bt like this

```
(lldb) bt
* thread #1, name = 'spectacle', stop reason = signal SIGBUS: hardware error
  * frame #0: 0x000000080246f67f
libQt5Core.so.5`QObjectPrivate::connectImpl(QObject const*, int, QObject
const*, void**, QtPrivate::QSlotObjectBase*, Qt::ConnectionType, int const*,
QMetaObject const*) + 735
    frame #1: 0x000000080246f287 libQt5Core.so.5`QObject::connectImpl(QObject
const*, void**, QObject const*, void**, QtPrivate::QSlotObjectBase*,
Qt::ConnectionType, int const*, QMetaObject const*) + 295
    frame #2: 0x000000080d9455a2
libKF5kipiplugins.so.5.9.1`KIPIPlugins::KPImagesList::KPImagesList(QWidget*,
int) + 3330
    frame #3: 0x000000081908bac3
kipiplugin_remotestorage.so`___lldb_unnamed_symbol106$$kipiplugin_remotestorage.so
+ 675
    frame #4: 0x0000000819088535
kipiplugin_remotestorage.so`___lldb_unnamed_symbol46$$kipiplugin_remotestorage.so
+ 101
    frame #5: 0x00000008190880c5
kipiplugin_remotestorage.so`___lldb_unnamed_symbol38$$kipiplugin_remotestorage.so
+ 293
    frame #6: 0x0000000802472b39
libQt5Core.so.5`___lldb_unnamed_symbol2439$$libQt5Core.so.5 + 1449
    frame #7: 0x0000000801292dfa
libQt5Widgets.so.5`QAction::activate(QAction::ActionEvent) + 314
    frame #8: 0x000000080141557d
libQt5Widgets.so.5`___lldb_unnamed_symbol1982$$libQt5Widgets.so.5 + 77
    frame #9: 0x0000000801412aab
libQt5Widgets.so.5`___lldb_unnamed_symbol1958$$libQt5Widgets.so.5 + 555
    frame #10: 0x0000000801419e60
libQt5Widgets.so.5`QMenu::mouseReleaseEvent(QMouseEvent*) + 704
```

which carries on from where Graham's bt trails off (I think in
mouseReleaseEvent). Just seeing that there's dynamic_cast<> in the code makes
me think I can guess a reason (there was a similar problem in kleopatra).
