Same or similar bug here:

KDE Platform Version: 4.8.4 
Qt Version: 4.8.4
Operating System: 3.9-1-amd64
Distribution: Debian Jessie

-- Information about the crash:
While parsing a project kdevelop crashes. Parsing crashes only when there are some C++ STL includes.

The crash can be reproduced every time.

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

(Yes, the backtrace was useless even with the dbg symbols installed)
Comment 2 Milian Wolff 2013-12-01 18:55:41 UTC 
Git commit 357f56d5502f0fafafed6e769f86e568cecb0bf3 by Milian Wolff.
Committed on 01/12/2013 at 16:27.
Pushed by mwolff into branch '1.6'.

Check the validity of currentAbstractType before accessing it.

Apparently there can be cases where m_gotTypeFromDocComment is true
but the type is invalid. To prevent crashes, we check this now and
fall back to the cases of m_gotTypeFromDocComment being false.
