This bug is very old, but removing qt-at-spi fixed qtiplot crashing on displaying an import/export dialogue which was suddenly appearing (from one hour to another without rebooting, updating, etc., according to the user) on an Ubuntu 16.04 (64-bit). Updating to the latest version and rebooting did not fix this problem, so I started googling and found this bug report..
