Comment 6 for bug 1837071

In my case xfsettingsd results segfault during the session startup:

[Tue Oct 8 11:14:22 2019] xfsettingsd[2538]: segfault at 18 ip 00007fc318301f2d sp 00007ffdcfc9f2d0 error 4 in libxklavier.so.16.4.0[7fc3182f7000+d000]

When I start xfsettingsd afterwards from xterm, it starts and functions correctly. I have difficulty capturing the backtrace with gdb unless somebody can give a hint how to do it. I have added

export XFSETTINGSD_DEBUG=1
ulimit -c unlimited
/etc/X11/Xsession

to ./.vnc/xstartup but it does not generate a core dump :(
