Bug#579490: akregator: nspluginviewer used in presenting feed items



Package: akregator
Version: 4:4.3.4-2
Severity: normal


When presenting feed items, I expect the presentation
to be somewhat sanitized. I expect no scripts to run,
for example. I've always had the impression that with
akregator this is the case (again: I am limiting the
scope to feed items, not web pages).

Recently I've found a disturbing phenomenon: large
CPU consumption by nspluginviewer invoked by akregator.
Today I've investigated a bit further, and I can link
it to one specific feed (perhaps others too, but this
one does it reliably and that should be enough). The
feed is at http://www.sisterclaire.com/?feed=rss2 and
the current feed document is attached.

The problem item is the currently newest item on this 
feed, so first in the attached doc. It includes embedded
Flash, which I suppose is what triggers the bad behavior.

Whenever I open the item in Akregator, I start seeing a
nspluginviewer process taking ~20% CPU. This process is
not gone when I switch to another item (on another feed,
where the item is plain text).

The 20% CPU is bothersome, but I'm more concerned with
the issue of the plugin viewer being started at all.

Thanks,
	Shai.
