I haven't heard of it before and can't think of any reasons why it
might be the case.  I tried reproducing it as well but couldn't
although I'm not sure that I understand what you mean by not being
able to access the namespace.

Can you give a more detailed set of steps of how to reproduce this and
more information about your environment (like the kernel version)?
