Not that I know of. (And we today had the same error at another user, who
didn't even know he was using IcedTea until I said him how to check, so I'm
quite sure he didn't change any security settings.)

There is no such directory. Without the 'ext', I have it:

-rw-r--r-- 1 root root 46632 2010-11-23 07:30
/usr/lib/jvm/java-6-openjdk/jre/lib/i386/libpulse-java.so

OK.

Does this means "apt-get remove --purge" and "apt-get install", or do I have to
do more? (Can't afford a new computer now.)

Took a bit longer to find some time, but now I'm "on it" ... expect it within
the next day.
