Bug 377962

Application: kate (16.12.3)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
test driving kde wayland again, as I do once in a while. This time kate crashed and the backtrace seems to indicate it's wayland-related. I opened a file with long lines (22275 chars max), clicked "Temporarily raise limit and reload file", scrolled around. 
After clicking close (x-symbol) kate crashes. 

Crash is reproducable.

Any more info I can provide?

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
