Right, this is on the server. With the Windows client there is no 
.bashrc anyway. I confirmed with my colleague that he saw this on both 
the Windows and Ubuntu Precise clients.

Which windowing system chosen on the server does not seem to matter 
either. I saw it with UNITY and with just "Terminal".

That's interesting. The reason for putting in the echo's was to debug a 
completely unrelated problem about which shell init got run when we were 
running some batch jobs. I had instrumented the init files before 
without difficulty. Thanks for looking at this.
