--------------------------------------------------------------------------
Ah sorry, we had a misunderstanding. I cannot take the 1.2 version. We need a
1.1 version.
If you recall, we cannot run 1.2 on RHEL5 due to glibc issues. Client is also
on 1.1 and in the short term is not interested in upgrading a production system
to 1.2, so it would be a very hard sell.
That is why if we want to ask them to help us to reproduce the issue, we need
to be able to do it with a 1.1 version.
