/etc/X11/Xsession.d/90qt-a11y causing gsettings to become a zombie process.

[wpreston]

From the initial investigation:

"/etc/X11/Xsession.d/90qt-a11y contains a single invocation of "gsettings get" which should not be even a little-bit controversial, yet somehow is causing gsettings to become a zombie process. A stack trace is unenlightening, and people who have a better understanding of the kernel and userspace than I do are out of ideas.

The quick-and-dirty fix is to simply divert that file out of the way, but that's clearly a band-aid, because the root cause has not been identified."

We have confirmed that diverting this fixes the issue.
