Bug 374522

Application: kate (16.08.2)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
In ~/.config/dcd/dcd.conf was:
/usr/include/dmd/druntime/import
/usr/include/dmd/phobos
~/.dub/packages/requests-0.4.0/requests/source

And after typing:
import requests;
...
MultipartForm form;
form.add⏎

Autocomplete works fine, but after choosing method and pressing "return" - kate crushed.

The crash can be reproduced every time.

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