Sentry Crash Report:

Description Andrew M 2018-08-11 12:55:15 UTC 
Application: kdevelop (5.2.3)

Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.17.11-arch1 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
Kdevelop crashes when loading up a project from the previous session and then the user closes that project during on of the parsing phases.

- What I was doing when the application crashed:

So I had a previous session with 2 projects open: The Linux kernel and a small single main.c file test project.
Opening Kdevelop I wanted to close the Linux project and leave the test project open. The test project appeared first in the projects pannel, then when the Linux project appeared I right clicked to close it before Kdevelop got stuck into parsing the billion files within. Closing it caused the crash.

Crashed twice in a row doing the same operation.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
