Description Matija Šuklje 2011-10-18 12:50:36 UTC 
Application: rekonq (0.8.0)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r3 x86_64
Distribution: "Gentoo Base System release 2.0.3"

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

1) start rekonq
2) see it crash

It doesn't even manage to show its main window.

I'm not sure if it's related, but I suspect it could be that I use an older Qt-WebKit.

KDE 4.7.1
Qt (including Qt-WebKit): 4.7.2

The crash can be reproduced every time.

-- Backtrace:

rekonq (0.8.0) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

Everytime rekonq is started it segfaults. This can be reproduced every time.

Git commit c8a48c13388b34099e8ee7704985d887b36acd0d by Andrea Diamantini.
Committed on 08/11/2011 at 12:42.
Pushed by adjam into branch 'NoPostLaunch'.

Remove postLaunch calls

This will help a lot in having a clean/easy startup, also a bit less
fast.
Let's see if this helps stability...

PS:
To the bug reporter. I pushed a "NoPostLaunch" in rekonq git repo.
Can you please try compiling and testing if this fixes your troubles
on startup??
Many thanks for any help.
Andrea.

The latest git version:
34cc0191f3e580685cc3f8b0b74160d5559544b2

The bug seems to be fixed. You have to wait for the distributions to package the new version.
