This happened to me again, running KDE 3.5.8 on openSUSE 10.3, I was trying to view a embedded flash video (the video can be found here http://javacrpg.sourceforge.net/ ) the backtrace that I got from it is as follows:

System configuration startup check disabled.

I know that KDE 4 is just around the corner, but I am just reporting this hoping that it can be checked against KDE 4.

I was viewing the following URL in Konqueror (Konqueror 3.57, KDE 3.57 release 72.4, SuSE 10.3): http://www.cbc.ca/ottawa/weather/index.html?station=YOW&style=ottawaFull

When I closed the window, I got a KDE error window saying that nspluginviewer had crashed with a signal 11 (SIGSEGV). No backtrace was available.

This happened several times in a row.

I can reproduce this bug in a current KDE4 SVN on www.arcor.de

Steps to reproduce:
1) goto www.arcor.de
2) let the page load
3) close konqueror
4) the nspluginviewer crashes with the following backtrace:

I'll attach a backtrace and a valgrind log for this crash.

Backtrace:
Application: nspluginviewer (nspluginviewer), signal SIGSEGV
