Description Benjamin Huth 2022-01-27 12:37:33 UTC

Application: kdevelop (5.8.220370 (22.03.70))

Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.15.16-200.fc35.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora release 35 (Thirty Five)"
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- Custom settings of the application:

KDevelop-python is built against a built of python 3.9.0, since the official python of my distribution (Fedora 35) is not supported by Kdevelop-python.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
