strange problem with java applets in firefox on NetBSD 5 STABLE

[Lasse Hillerøe Petersen <lhp%toft-hp.dk@localhost>]

I have recently installed NetBSD 5_STABLE and a load of packages from pkgsrc, 
including firefox, openjdk and icedtea.
Previously, I was using jdk15 from wip, and the old java-plugin, I suppose.

I am using a banking solution which apparantly stores a keystore locally; this 
used to work fine, however now I get permission errors.

I found a page mentioning similar problems (but on Ubuntu, and offering no 
solution: http://www.keyongtech.com/4526314-good-news-update-on-java), and a 
link to a test page, which I tried, getting the same error.

Entering this page with a browser started from a terminal, I get this on stderr:

A little system info:

I had tested applets on the java.sun.com page, and found no problems, so I have 
deleted my old setup. :-(
Right now, I am thinking about how to find out whether it is the icedtea 
plugin, og the JDK that is causing the problems.
As I very much need access to my bank, I would appreciate any kind of help and 
suggestions.
