FYI,
KDE SIG is investigating some recent/serious reported crasher bugs in
rawhide, notably:
"Could not sync environment to dbus." (startkde)

and (an older one, but the situation has gotten worse recently):
Qt5 application crashes when connecting/disconnecting displays
https://bugzilla.redhat.com/show_bug.cgi?id=1083664
https://bugreports.qt.io/browse/QTBUG-44388
Initial theories are that gcc5 landing may have something to do with it,
since the recent crashes go away reverting to pre-gcc5 builds of the same
packages.
While gcc 5.0 exposed some issues in the Qt codebase which are actual
bugs (reported in the above linked QTBUG-44388), there is also
definitely a compiler bug involved here (one hint of this being that I'm
able to compile c++ code with a derived class method calling a private
function of a base class). I'm currently trying to narrow down the
issue. In any event, this bug is causing most Qt5 applications to crash
right on start (regardless of the display configuration).
