Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-34-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
When testing an python application i had written and trying to stop it with the stop all button KDevelop crashed after a 1/2 second delay.
This happens about 85% of the time when trying to reproduce it.

Custom launch configuration which launches the current file in the editor.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted

This may be a duplicate of https://bugs.kde.org/show_bug.cgi?id=368420 which was fixed in 5.2.2.

Backtrace does look quite different though, so perhaps not, but I can't reproduce the problem with 5.3-git.

Please try with a current version from https://www.kdevelop.org/download (or nag your distro to upgrade their package with recent bugfixes) and see whether that solves the problem.

Thanks for the report.

Downloading KDevelop 5.2.4 from https://www.kdevelop.org/download fixes the problem.
