Thanks for replying.  In fact, I have libxcb-cursor0 installed as well which
was not picked up by reportbug:

,----
| $ dpkg -l | grep xcb-cursor0
| ii  libxcb-cursor0:amd64                                0.1.5-1               
               amd64        utility libraries for X C Binding -- cursor
`----

Also I notice that if I continue to launch the qbittorrent process, the crash
might happen quite a few times and then it will stabilize eventually
and run stably after, which is quite puzzling.
