I can confirm the problem. nspluginviewer crash is reproducible not only on youtube but on any page that contains flash objects. As indicated on the report, a page reload is enough.

Comment 2 Gualter Barbas Baptista 2011-12-02 11:33:00 UTC

Similar problem was reported in #273323 and a patch was submitted. However you report being using KDE 4.6.5, where this should have been already active.

This is definitely a serious problem - and it is recurrent with Konqueror/KDE for the last years -, taking into account how many people use Flash.

I added Maksim Orlovich, if he can help with this as in the https://bugs.kde.org/273323

Comment 4 Dimitrios Glentadakis 2012-01-07 14:24:36 UTC

I tried today the latest version 11-2 of the plugin from adobe
http://labs.adobe.com/downloads/flashplayer11-2.html

Until now i dont have any crash. Can you confirm this too ?

Comment 5 Dimitrios Glentadakis 2012-01-10 20:33:34 UTC

No crash until now (3 days) it is clear that the problem is solved
