kdeinit5 crash window in blank plasma session

observation:
blank and unusable plasma5 session, only error window about kdeinit5 (see
screenshot)

steps to reproduce:
 1. virt-install --name opensuse_leap --ram 2048 --disk
path=~/local/virtual/opensuse_leap2.qcow2,size=8 --vcpus 1 --os-type linux
--os-variant generic --location
'http://download.opensuse.org/distribution/leap/42.1/repo/oss/'
 2. wait for end of installation and first boot
 3. observe error

problem:
I reproduced this problem using virt-install (three times) based on the online
repo, one time using the virt-manager install helper using the dvd-iso as well
as on Tumbleweed (TODO ref bug).
different hypotheses (Hx):
 - H1: plasma erroneously detects 3D acceleration available which is not in
virtual machine
 - H2: could be related to https://bugzilla.opensuse.org/show_bug.cgi?id=949978
 - H3: Something related to my host environment


suggestions:
experiments (Ex-y) corresponding to hypotheses (Hx):
 - E1-1: Try with different backends or virtualization solutions, e.g.
virtualbox
 - E3-1: Someone else reproduce it
