Comment 1 Christoph Feck 2017-10-12 17:58:31 UTC 
Crash could be caused by AtSpiAdaptor accessibility code.
Comment 2 Denis Kurz 2018-01-31 16:11:05 UTC 
You might want to consider if this was caused by a Qt bug that was resolved fixed in 5.8, as described in Bug 361895, Comment 1.
Comment 3 Christoph Feck 2019-05-14 00:41:19 UTC 
Fixed in Qt 5.6.3 according to https://bugreports.qt.io/browse/QTBUG-58153
