--- Comment #1 from RJVB ---
(drKonqi balks something about private attachments not being allowed when I
try to upload the latest report, so here it is manually):
Application: kdevelop (5.5.0-25-g0dda64acb3)
(Compiled from sources)
Qt Version: 5.9.8
Frameworks Version: 5.60.0
Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64
Windowing system: X11
Distribution: Ubuntu 14.04.6 LTS
-- Information about the crash:
- What I was doing when the application crashed:
As the previous time, I quit KDevelop and a deadlock ensued after the
languageController was cleaned up.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
