Application: kdevelop (4.7.1)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.16.0-23-generic x86_64
Distribution: Ubuntu 15.04

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

I had searched for uses of a function, then switched to another application. After a few minutes in the background, KDevelop crashed.

KCrash writes "every time" below, but for clarity I'll add that this specific pattern was only seen twice. I suspect that my other bug report has the same cause, however.

The crash can be reproduced every time.

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