Description Hrvoje Senjan 2011-10-14 12:58:13 UTC 
Application: akregator (4.7.2)

Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Opened a news feed in a new tab (KDE's 15th aniversary news on dot.kde ;) ), and when i tried to close it , akregator crashed. This usually doesn't happen, altough i check the feeds in a regular browser.

-- Backtrace:

akregator (4.8 pre) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

- What I was doing when the application crashed:

This happens every time I close a tab with a web page open in it.  It didn't happen with trunk from a week or so ago, but does now.

*** Bug 284538 has been marked as a duplicate of this bug. ***
Comment 3 Christophe Marin 2011-10-20 10:55:18 UTC 
As I cannot reproduce, I suppose it crashes only when webkit is the rendering engine ?
Comment 4 Jonathan Marten 2011-10-20 11:13:35 UTC 
Apologies for the duplicate, but the bug reporting wizard didn't find any matching ones...

Not sure where my setting for WebKit came from, there is no option in Akregator to change this.  The Konqueror setting in Settings - Configure Konqueror - General was indeed set to WebKit, but I have no recollection of ever changing this.  The odd thing was that even though this was set to WebKit, opening any web page in Konqueror would display in KHTML (according to the View - View Mode menu).

Changing this setting back to KHTML appears to fix the problem in Akregator.

kontact (4.7.2) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

As described above. akregator/kontact crashes every time when closing a tab when webkit is used as rendering engine (which is the new default with KDE 4.7.2  to my knowledge, at least for openSUSE). That konqueror still use khtml when clicking on a link was only present for me because this was an old home and caused by the content of ~/.kde4/share/apps/konqueror/profiles/webbrowsing

Dirty patch to get a working Akregator with kwebkitpart

It's a quick and dirty patch which corrects locally the bug. As I'm not a KDE developper, I can't find the root cause of the problem (kdelibs ? kwebkitpart ?)

Comment 13 Mat Lechner 2011-11-08 14:24:17 UTC 
I also experience this bug since the 4.7.2 to 4.7.3 update. Sometimes, I can close every tab but the first one, but mostly it crashes if I close any of the tabs.

(I did not attach a backtrace, since its basically the same as the others)

> Is there an opensuse repository or rpm so I can test it without compiling?

In general it makes more sense to ask these questions at the openSUSE bugzilla, mailinglist, etc as upstream as you do not even tell with openSUSE version with which repos you use. But in this case there is already an openSUSE bug (https://bugzilla.novell.com/show_bug.cgi?id=729829) open for this issue with a link to an repo with fixed packages where I am waiting for feedback. So if you have specific needs please ask there.
