Bug 377631

I get a segmentation fault every time I close KDevelop (5.04).

About KDevelop (and KDevelop Platform) state:
KDE Frameworks 5.32.0
Qt 5.7.1 (built against 5.7.1)
The xcb windowing system

My system is:
KDE neon User Edition 5.9 (xenial 16.04)
KDE Plasma Version 5.9.3

The backtrace is:

Thread 3 "QDBusConnection" received signal SIGSEGV, Segmentation fault.
