For discussion of the same issue for another application and DSO, see:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=178924
and
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170187

Can you run 'execstack -c' on the shared object?  If that succeeds, does
the program then work?  Also, check your /var/log/audit/audit.log for
any other AVC denials.
