Comment 1 Christoph Feck 2015-05-06 21:07:16 UTC 
Your system is messed up.

Here, a KDE4 application tries to load a plugin from KF5. This can happen if you mix the  library path configurations, or if the ld.so.cache is corrupted. If you are unsure how to fix this, please ask for help in a forum of your distribution.

This is probably also the cause for the Plasma crash you get, e.g. bug 347229.

In the future, please do not report the same bugs multiple times. It does not raise our attention, but only increases our workload.
Comment 2 Kevin Coonan 2015-05-07 15:58:21 UTC 
I realize that my system is messed up.  The crash when I try to log in was my first clue.  If you read the bug reports, you see that I have been attempting to fix the problem following various forum instructions.

Wouldn't it be useful to provide some sort of pattern matching (um, I dunno, a REGEX) that took identical bug report traces and incremented a counter when other key information matched?  Would save you work, and give you an idea of the scope of the problem.

Having a simple script which fixes this problem (which, from the various forums for SuSE, Ubuntu, Arch, KDE, etc. etc. is ubiquitous) would be very welcome--you just pick which version of KDE you want and it cleans out the conflicting packages?  Sure as hell would be an improvement in going down the list in YAST2 and removing every package with KF5, and switching the version of each KDE core/related package to 4.14.6 (I couldn't find any documentation why some of the packages have version numbers like 14.x.y-j.k or 15.x.y-j.k rather than 4.a.b.c-j.k--so I opted to go with what seemed to be the most conservative path).  It only took about 6 hours to complete (fortunately, I have fast download speeds and a  SSD), and another 4 or so to verify and correct those packages which didn't get switched the first time...
