Description
I am running Fedora 26. Attempting to run QGIS 2.18 Las Palmas results in an error message:
Couldn't load plugin MetaSearch due to an error when calling its classFactory() method
RuntimeError: PyKDE4.kdeui cannot import type 'QList >' from PyQt4.QtCore

Starting QGIS from a console command line using --noplugins results in a start with no reported problems.

and had no issues.

I installed from the same source, following the same directions, and the bug report (16963) is the product of that process. So, the fact that you had no troubles is not informative to me. And on my system, Las Palmas still crashes on startup.

Any chance to try on a different system, maybe a VM? Is the whole QGIS that crashes or is just the metasearch plugin that returns a python error?

If I close the error message, the banner simply vanishes while "Restoring loaded plugins." I've been experimenting and curiously, if I try launching a second instance, the QGIS GUI comes up. However, attempting to install plugins brings it down. Monitoring the processes shows qgis until the banner vanishes and then that process disappears.
The error explicitly notes:
PyKDE4.kdeui cannot import type 'QList >' from PyQt4.QtCore
That suggests to me that my preference for KDE might be part of the problem, but ...
I was running both QGIS 2.18 and GRASS using Opensuse Leap 42.2 (KDE version) before I had some sort of problem with the system that left it partially bootable. I decided to do a clean install of Fedora 25 (KDE spin). I had not tried installing either piece on the "25" system before the "26" update came out. There were no hardware changes.
I can also start QGIS from a terminal using the "--noplugins" option.
Running (well trying to) QGIS from the console, the final error messages qre:
QH6248 qh_lib_check: Incorrect qhull library called. Caller uses reentrant Qhull while library is non-reentrant
QH6249 qh_lib_check: Incorrect qhull library called. Size of qhT for caller is 8184, but for library is 2896.
QH6256 qh_lib_check: Cannot continue. Library 'qhull 7.2.0 (2015.2 2016/01/18)' uses a static qhT (e.g., libqhull.so)
This seems to the reappearance of an older problem. One reported solution was to downgrade from qhull 0.19 to 0.11. I tried that with no success. The PyKDE4 error continues to appear.
Thanks for thinking about this.

Just to add my experiences on this issue. I think this is really a Fedora 26 Bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1480727
When you just use Python and try to import import PyKDE4.kdeui you get an error. I think this was because PyQt4/pykde4 were built against an older version of sip:
