Sentry Crash Report:

Description Thomas Murach 2016-11-17 09:16:20 UTC 
Application: kdevelop (5.0.1)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.1.34-33-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
KDevelop crashes very often when I start it; for example after starting it for the first time after booting my machine in the morning, it will always crash. When starting it again after a crash I'm asked whether I want to delete the cache. If I remember correctly, not clearing the cache will always lead to another crash at some point. Clearing the cache at least increases the chance of a successful startup, although also in this case it crashes often.
From my experience crashes occur at a stage where something on the order of 1-20% of the files in the project folder have been scanned, I've rarely seen crashes at much higher percentages, but maybe I'm just lacking statistics here.

I'm happy to provide more info if needed.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
