test file that caused the crash.

Description dan 2011-01-04 17:44:28 UTC 
Application: kdevelop (4.1.80)
KDE Platform Version: 4.5.90 (4.6 RC1)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-11-generic x86_64
Distribution: Ubuntu natty (development branch)

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

Starting the application and a project (only one) was already loaded.  It then crashed.  I made sure I loaded all the debug symbols I could find, but I think there could be some sort of javascript error inside Qt or such.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault

Created attachment 55571 [details]
New crash information added by DrKonqi

kdevelop (4.1.80) on KDE Platform 4.5.90 (4.6 RC1) using Qt 4.7.1

- What I was doing when the application crashed:

Started the application with a new session even after wiping out existing kde settings.

-- Backtrace (Reduced):

Comment 2 Milian Wolff 2011-01-06 12:38:41 UTC 
probably upstream bug, see also https://bugzilla.redhat.com/show_bug.cgi?id=648319

how much memory do you have in your machine?
Comment 3 dan 2011-01-06 17:53:25 UTC 
4G of ram here
Comment 4 Danni Coy 2011-02-16 12:38:54 UTC

test file that caused the crash.

also after crash - kdevelop crashes continually on startup
Comment 5 Milian Wolff 2011-02-16 14:20:27 UTC 
*** Bug 266438 has been marked as a duplicate of this bug. ***
Comment 6 Milian Wolff 2011-02-16 15:20:19 UTC 
Danni: if this is reproducible, please run KDevelop through valgrind and show us the log it produces.
Comment 7 Danni Coy 2011-02-17 05:36:51 UTC 
here you go. Yes basically crashing until I delete the session file in ~/.kde/share/...

Comment 8 Milian Wolff 2011-02-17 10:41:46 UTC 
nothing we can do - it's an upstream bug. Apparently it might be fixed already with this:

http://trac.webkit.org/changeset/77025

Question is which Qt version will include that fix - I'm waiting for a response by the trolls.
Comment 9 Danni Coy 2011-02-17 10:58:49 UTC 
Is webkit used by the core - or is it a plugin I can disable for now?
Comment 10 Milian Wolff 2011-02-17 11:34:18 UTC 
you can try to disable the Man-Page documentation plugin.
