            Bug ID: 389051
           Summary: Crash while editing a file
           Product: kdevelop
           Version: 5.2.1
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdevelop-bugs-n...@kde.org
          Reporter: keithwilliams...@gmail.com
  Target Milestone: ---

Application: kdevelop (5.2.1)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.13-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
kdevelop crashed while editing a file.  I restarted, using the existing cache
as I wanted to recover my changes.  I was able to save changes, but every time
I  pressed a key when one particular file was in view, it crashed. 

The session was initially started from a newly created project from an existing
makefile.

Using ArchiLinux distribution of Kdevelop 5.

The crash can be reproduced every time.

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