Bug 445565

Application: kdevelop (5.6.2)

Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.14.14-2-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I was just editing a member, deleting something old and starting to write something new.
I noticed that it stopped to refresh and react to keystrokes, and then the crash.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = {<No data fields>}}
