Application: kdevelop (4.7.1)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 4.1.6-2.gce0123d-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

I started kdevelop from the application launcher menu. I believe the last time I ran kdevelop, it was an older version, perhaps from 4-9 months ago. I generally update to whatever's newest of opensuse 13.2 and the KDE:Extra repository in the open build service for 13.2.  The majority of the settings for kdevelop are default, though I've tweaked some colors and things in the text editor component shared with Kate.  I don't think anything specific to kdevelop is outside of the defaults.

The crash can be reproduced sometimes.

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