Comment 2 Thomas Lübking 2015-05-03 09:08:42 UTC 
Looks like an unresolved symbol, ie. the breeze plugin was compiled against libkdecorations 5.3 but resolves the 5.2 binary.

Check
   stat /usr/lib64/libkdecorations2.so.5
and the contents of /usr/lib64/

There should be /usr/lib64/libkdecorations2.so.5.3.0 or some late beta at least and that better be linked by /usr/lib64/libkdecorations2.so.5 and /usr/lib64/libkdecorations2.so
Comment 3 Martin Flöser 2016-08-29 06:58:54 UTC 
Looks like the issue was caused by the upgrade situation.
