New crash information added by DrKonqi

partitionmanager (4.1.0) using Qt 5.12.8

- What I was doing when the application crashed: Simple trying to interrogate usb drive with partition manager. Tried directly selecting, immediately crashed, tried stepping through from sda sdb sdc and on sdd crashed. Tried upward sdg, sdf, sde and sdd crashed.
Tried usin drop down and crashed immediately.
Initially only partition manager in use, latterly bug report and firefox minimised.
