Package: qbittorrent Version: 3.1.0-1 Followup-For: Bug #726803 I think I'm having the same problem, although without having run a debugger session. I upgraded qBittorrent from v3.0.11 to 3.1.0 (on /usr/local/) and 3.1.0-1 (on /usr). Both new versions seemingly start, at least I get no error message. pstree shows me a running process managing 6 threads. But that's all. The GUI won't appear, and in the tray the space for an icon gets reserved, but no icon appears and it is only possible to kill qbittorrent explicitly via kill or killall. I can't find anything in the logs that might be connected with this problem.
