Description Piotr Mierzwinski 2015-02-19 13:44:35 UTC

Application: kdevelop (4.7.1)
KDE Platform Version: 4.14.5
Qt Version: 4.8.6
Operating System: Linux 3.19.0-desktop-1.mga5 i686
Distribution: "Mageia 5"

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

1. I've closed project.
2. I've removed ~/.cache/kdevduchain
3. I've opened before closed project
4. I've ciicked on main directory in project view.
5. KDevelop was starting build kdevduchain (directory has been created and a lot of files inside as well, what seemed look like old kdevduchain including weigh ~71MB)
6. Suddenly KDevelope crashed

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/i686/libthread_db.so.1".

Request refers to KDevelop 4.7.1
Running on Mageia 5 beta 2 (including latest updates on the moment of crash)
Attached terminal output from KDevelop session, what KDevelop printed during work.

Comment 2 Piotr Mierzwinski 2015-02-19 13:51:14 UTC

Created attachment 91173 [details]
output what kdevelop printed during work in this session

Comment 3 Kevin Funk 2015-08-25 08:08:35 UTC

Never a good idea to kill an application's cache while it is running...

Comment 4 Piotr Mierzwinski 2015-08-25 12:26:02 UTC

Yes your right. This might be only accidental action. I close it.

For me much important is fixing this one:
https://bugs.kde.org/show_bug.cgi?id=334487
and this https://bugs.kde.org/show_bug.cgi?id=350003  (annoying closing opened documents when I try to review them, what is the same broke in KDevelop 4.90.90)
