Description Bartosz Brachaczek 2012-04-25 14:17:11 UTC

Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.2 (4.8.2) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.3.0-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

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

I had a couple of tabs opened with a large C++/Qt project (Kadu). Accidentally I closed one which I needed (it was a header with class definition), and opened it again through the Recent files menu. Then KDevelop crashed.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
