Description bzhbok 2010-02-11 22:51:12 UTC 
Application: rekonq (0.3.0)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.32-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I'm using Arch linux with "kdemod testing" repository

I tried sevreal version of rekonq :
kdemod-rekonq (0.3.0-3)
aur/rekonq-git (0.3.0-1) (built from source)
rekonq from kde-apps.org (0.3.90) (built from source)

All of them were VERY unstable on my machine : most of the time crash at startup (except version 0.3.90 or if launching rekonq with a website as argument ex: "rekonq www.kde.org"). If it survives startup, it crashes when changing of webpage with a very high probability (>40%). It may depends on which page I'm going. I've never been able to browse 10 webpages without this crash.

If launched from a shell, I always get a log that finish the same (see attachement)

Apparently somebody else encounter a problem similiar to mine:
http://www.mail-archive.com/rekonq@kde.org/msg00974.html



The crash can be reproduced every time.

Ok, by looking at the trace, I found the cause of the problem : flash plugin
And the version of flash installed was : flashplugin 10.1-prerelease
I installed the stable version (flashplugin 10.0.42.34-1) and now I don't have this problem anymore :-)

Sorry for blaming rekonq for that... (although a flash plugin isolation like in Chrome would be nice in a futur release ;-) )
