Comment 1 András Manţia 2009-12-01 17:36:43 UTC 
I see the same crash, 100% reproducible for this page (when clicking on the planetkde.org feed, but doesn't crash in Konqueror itself):

Comment 2 András Manţia 2009-12-02 11:14:28 UTC 
Attached patch workarounds the bug, although it is not the real fix. I have a feeling the crash happens in KHTML when plugins are disabled and a page with a flash content is loaded.

Workaround
Comment 4 Alex Merry 2009-12-05 18:47:18 UTC 
What do you mean by "plugins are disabled"?  I get it every time I load a feed entry in Akregator that has flash content (eg: http://vizzzion.org/blog/2009/12/konstipation/ on the PlanetKDE feed), but I have "plugins enabled globally" checked in Konqueror's settings.
Comment 5 Alex Merry 2009-12-05 18:52:30 UTC 
The patch does indeed fix it for me.

My build from a few days ago (including, I believe, a version of Qt from slightly before 4.6.0) didn't have this problem.

Comment 7 András Manţia 2009-12-06 11:33:40 UTC 
I mean this might happen when plugins are disabled for the specific KHTMLPart ,like it is in this case:
    m_part->setPluginsEnabled(false);

This is not related to your configuration settings. But this is just a guess, I didn't have time to test with a simple testcase, that's why I did not commit the workaround.
Comment 8 Jaime Torres 2009-12-06 11:46:47 UTC 
Your patch also works for me.

morten's "Take it with a grain of salt" post is causing this crash. I'm using trunk from yesterday, and just updated kde-qt too.
Comment 13 Andreas Pakulat 2009-12-18 09:38:20 UTC 
Getting this too. The pages work fine in konqueror itself though, even if I disable plugins globally there. Last time I used akregator from trunk is probably about 2 weeks ago.

Comment 15 Michael Seiwert 2010-01-01 18:07:18 UTC 
Could anybody please explain why the plugins are disabled for this part ? Are this security reasons ? I have experimentally set m_part->setPluginsEnabled(true) and flash content is showing up nicely.

Qt commit 70496884450d3989829a63baac8db48d36190a25 available in Qt 4.6.1 should fix this, if I understand the backtrace correctly.

Comment 20 Michael Seiwert 2010-01-20 07:11:21 UTC 
New bt akregator compiled with qt 4.6.1 (kde-qt master branch from gitorious)

Patch: m_part->view()->setAttribute(Qt::WA_InputMethodEnabled, true); in articleviewer.cpp was commented out, but if enabled fixes the crash for me.

Akregator 1.6.5 / KDE 4.5.5.
Today I've started using WebKit as an engine for Akregator.
Crashes still occur on pages with Flash content.
