--- Comment #2 from Peter Mattern <pmattern at arcor.de> ---
This problem seems to be due to some incompatibility of the swrast DRI drivers
in Mesa 3D 11.1.2 with glibc 2.23.

It does not affect either Konsole or KDE as a whole only but among other all Qt
applications and the X server.
FWIW I've been posting some detailed findings on Arch Linux at
https://bbs.archlinux.org/viewtopic.php?id=209466. Note attributing these to
QEMU was probably wrong. Meanwhile I saw the findings including the traces are
e. g. the very same on a laptop featuring some VIA IGP making use of the swrast
driver, too.

A workaround and test is downgrading glibc to 2.22. The solution is to upgrade
the DRI driver to latest VCS. On Arch Linux the latter is provided by the
packages of pkgbase mesa-git which rely on the ones of pkgbase llvm-svn, all
from the AUR.
You may want to check this out.

All these findings were trial and error on Arch Linux after running into the
problem and looking through the logs, glancing through the Git log of Mesa 3D
since release 11.1.2 didn't yield a commit addressing the problem directly.
So any technical information what exactly is going on here would be much
appreciated.
