Comment 1 Nicolas Fella 2019-02-03 12:27:57 UTC
I cannot reproduce it with said image in a virtual machine. Also the backtrace looks very unspecific to KDE Connect (it crashed right at the start).

I'm not sure how to proceed
Comment 2 opensuse.lietuviu.kalba 2019-02-04 08:20:52 UTC
Indeed it seems to be some more unspecific to kdeconnect, but strongly related to logout process. I also can not reproduce every time. From about 10 or more times, I get this crash for kdeconnect about 4 times. But kdeconnect crash reappears at re-login also at these times.

Two other times was for dolphin, but I can not report but for dolphin, because Dr.Konqi crash dialog also closes right before aprearance of SDDM screen.
Comment 3 opensuse.lietuviu.kalba 2019-02-04 08:23:16 UTC
I also use virtual machine (VirtualBox). Somehow kdeconnect crash more often happens if I enable Bluetoth USB dongle in virtual machine.
Comment 4 Christoph Feck 2019-02-22 17:21:01 UTC
This seems to be a bug with XCB accessibility integration. I suggest to report this issue directly to Qt developers via https://bugreports.qt.io/
