Application: kdevelop (5.2.1)
Qt Version: 5.7.1
Frameworks Version: 5.40.0
Operating System: Linux 4.14.13-gentoo x86_64
Distribution: "Gentoo Base System release 2.4.1"

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

I pressed Enter in kdevelop, trying to accept an autocomplete suggestion.

Have also had crashes in kwrite recently (since last updating) when pressing Enter, but not trying to accept any autocomplete suggestions. I'm guessing it's the same issue.

If restarting kdevelop (or kwrite) and pressing Enter in the same place without editing too much, it sometimes crashes consistently.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
