Bug 452060

I run git-master frameworks/plasma/(most)-gear, including konsole, using the gentoo/kde overlay's live-git ebuilds.  The below plasma-integration commit triggers a konsole segfault before it even displays a window (on wayland if it matters).  I don't have symbols installed but a backtrace says the segfault is in wl_proxy_get_version() from libwayland-client.so.0,  in ?? in from KDEPlasmaPlatformTheme.so, which belongs to plasma-integration, so (after I found libwayland-client.so.0 belonged to wayland-1.20.0, which hadn't been upgraded since December) I began bisecting plasma-integration.  There were only three candidates to check including my previous-install commit, so it went pretty fast and it bisected to the below commit, still current HEAD.
