Description Dan Weatherill 2016-08-25 21:16:07 UTC 
Application: kdevelop (4.7.3)
KDE Platform Version: 4.14.22
Qt Version: 4.8.7
Operating System: Linux 4.7.0-2-default x86_64
Distribution: "openSUSE Tumbleweed (20160812) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
write any function call from an included file, press CTRL+SPACE to invoke code completion, segfault. 

Seems stable otherwise

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
