Bug 431289

Application: kdevelop (5.6.1)

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.10.4-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

Make some code with Main.cpp includes/Header.h and Makefile
Run KDevelop
Open Main.cpp
It looks for missed Header.h, select Solution 1 - Open Project
Select Makefile, Create Project
KDevelop crashes

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
