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


Application: nspluginviewer ()
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-28-generic i686
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
<In detail, tell us what you were doing  when the application crashed.>

The crash can be reproduced every time.

 -- Backtrace:
