Sentry Crash Report:

Description rjwgnr27 2014-02-18 23:54:06 UTC 
Application: kdevelop (4.6.60)
KDE Platform Version: 4.11.5 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.12.11-201.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
Opened an existing development tree as a new "Generic Project Manager" project. While the tree is being scanned, expanded a directory under the project under "Projects" tab.

To prune the size of the managed project (the development tree is quite large), I right-click on some of the directories not applicable to my work, and select "Exclude Item From Project". This will work a few times, then KDevelop crashes.

The crash can be reproduced every time.

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

Reported using DrKonqi
Comment 1 Valerio Pilo 2014-10-28 10:47:16 UTC 
Also happening to me, 100% reproducibility on big projects (during scan).
Crash handler report (didn't work automatically):

Application: kdevelop (4.7.0)
KDE Platform Version: 4.14.1
Qt Version: 4.8.6
Operating System: Linux 3.16.0-23-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
- What I was doing when the application crashed:
While importing a big project, I tried excluding some directories from it to speed up parsing.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
