Comment 20 for bug 115970

I also have a problem in 8.10.

I have identified at least the following programs not running: skype, last.fm, virtualbox.

I have not installed nessus so the solution provided in some forums does not apply.

Following the posts in this thread, I have tried to extract some extra information:

My /etc/ld.so.conf:

include /etc/ld.so.conf.d/*.conf

/usr/lib
/usr/local/lib
/usr/local/lib/siscardplugins

Some ldd messages:
