Another user experienced a similar problem:

Either closing or opening a file. 2 files had been open. Resorted to using Kwrite because of similar issue with Kate. Now both editors are not working.

Comment 17 mrh 2015-12-14 19:12:47 UTC 
Console messages from kate for opening an existing session. What's interesting is that every file is has been marked as as C++ syntax when they are perl, awk, latex, bash files, etc. This behaviour is new as I've been using this particular session for considerable time.

Comment 21 Reartes Guillermo 2015-12-28 12:20:57 UTC 
If one tries to save anything they crash. I do use them alot.
kate / kwrite are unusable ATM.

Even Konsole 'save as..' is affected, so be CAREFUL if you have other important tabs open... (use screen if you have remote connections...)

ATM i am using JuffEd, wich is similar and does not crash.

I tried strace kwrite:

the real bug is
https://bugzilla.redhat.com/show_bug.cgi?id=1291003
I reported there, but the maintainer seems to be unreachable at the moment. You can fix this locally for you by importing the gap-stopper (patch and spec can be found in that bug)
http://code.qt.io/cgit/qt/qtbase.git/commit/?h=5.5&id=37b7c5164c830458ea833d3757ca94cb7bebcb3a
into qt5-qtbase and recompiling and reinstalling the RPM.
