Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---
Application: kdevelop (5.5.0-19-gca0f71e796)
(Compiled from sources)
Qt Version: 5.9.8

-- Information about the crash:
- What I was doing when the application crashed:
Periodically, KDevelop will hang after (as far as I can determine) terminating
its core shutdown procedure (DUchain, sessionController and languageController,
in that order).
I don't see anything related to KDevelop in the backtrace or when I attach a
debugger; has anyone seen similar cases
The crash can be reproduced sometimes.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
