Sentry Crash Report:

Description OlafLostViking 2017-06-17 08:38:21 UTC 
Application: kdevelop (5.1.1)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.5-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I returned to my code view after debugging with a breakpoint set. There I edited some code and wanted to set a new breakpoint. After clicking into the icon bar the breakpoint appears at a totally different place (potentially due to inserted/deleted lines of code) and KDevelop crashed.

- How to replicate:

While I didn't manage to let KDevelop crash again, you can at least see the breakpoint problem by setting a breakpoint, inserting some lines before it and then setting another breakpoint/deleting it. The positions will be messed up.

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".
