Sentry Crash Report:

Description RJVB 2019-06-15 07:30:27 UTC 
Application: kdevelop (5.3.2-18-gfc20162935)
 (Compiled from sources)
Qt Version: 5.9.8
Frameworks Version: 5.54.0
Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.6 LTS

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

Here's a very strange backtrace for a crash I just got exitting KDevelop 5.3.2(git). The immediate reason is calling deleteSelf() method on a NULL instance, but I don't see how that point can have gotten to be NULL.

Is this just a freak event, or is there something in removecDocumentChainFromMemory() that can cause its context argument to become NULL?

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
