Description Robert Simmons 2011-06-19 18:06:57 UTC

Version:           1.6.6 (using KDE 4.6.4) 
OS:                Linux

If you load a feed, and the articles that the feed points to on the web contain flash content, the plugin, nspluginviewer, that Akregator uses to display that flash content crashes every time it tries to display the content.

For example most all of the articles on this feed have flash content that crashes the plugin:
http://exiledonline.com/feed/rss/

Also of note is that it does not crash immediately if the flash content is not initially visible in the display window.  It only crashes when you scroll down and make the flash content visible.

I have the flash plugin from Adobe installed, perhaps there should be a way to choose to use it rather than this one that is crashing?

Reproducible: Always

Steps to Reproduce:
Open Akregator
Load this feed:
http://exiledonline.com/feed/rss/
Follow one of the articles to the website using the link in the feed article.
If the flash content is not visible, scroll down the page, when it is visible the plugin will crash.

Actual Results:  
Segmentation fault every time

Expected Results:  
Properly displayed flash content

Here is the output of the backtrace:

Comment 1 Christophe Marin 2011-07-07 21:58:33 UTC

I cannot reproduce the crash with the articles with some flash content

Comment 2 Brian 2011-07-14 16:21:47 UTC

I have the same issue, nspluginviewer segmentation fault and crash on every load of a youtube (or any) flash object in Konqueror.  I am using a fresh install of Kubuntu 10.04 with only the recommended packages suggested on the first load of Konqueror ( the auto recommended packages you might be prompted to install on first load of konqueror, amarok etc ).  The computer is a brand new HP Probook 4525s, amd 64.  I am pasting the crash details below.

Actual results: Crash every time

Expected results: Display flash content
