Bug#803212: KDE affected in general, not just kate

[Gregor Riepl <onitake@gmail.com>]

I see the same crash since my last package upgrade (today).

And it affects not just kate, but _all_ of KDE 5: plasmashell, sddm, konsole,
you name it. The crashes produce different backtraces sometimes, but in
general, it happens after xcb_intern_atom or XInternAtoms. konsole still uses
KDE framework 4 AFAIK, so it calls out to libx11, not libxcb.

Could this be a bug in Xorg?
