Sentry Crash Report:

Description l_bilo 2012-08-13 15:27:55 UTC

Application: kdevelop (4.3.1)
KDE Platform Version: 4.9.00
Qt Version: 4.8.2
Operating System: Linux 3.4.7-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Running an outside build script, which amongst other things, deletes and recreates certain folders belonging to an open project inside Kdevelop.

I would focus on the backtrace from Thread #1, which fails @ KDirWatch::addDir.

- Unusual behavior I noticed:
Kdevelop always crashes, this has happened for a very long time on every Kdevelop version.

- Custom settings of the application:
Nothing relevant.

The crash can be reproduced every time.

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