Does Bash follow man bash INVOCATION conventions?

[Larry Alkoff <labradley@mindspring.com>]

Using Knoppix 3.8 and setting up my customizations for saveconfig.

I put echo statements in /home/knoppix.bashrc and /etc/profile to see 
how they run.  Knoppix is otherwise virgin.

When I click on an xterm I get the following display:
executing /etc/profile
executing ~/.bashrc
executing /etc/profile

Why is bash executing /etc/profile when I click on Konsole in KDE which 
is a "non-login" shell?

I see that ~/.bashrc sources /etc/profile which explains why it runs 
after .bashrc but why does it run the first time?

According to man bash INVOCATION section:

An interactive logon session reads/executes /etc/profile if it exists,
then reads/executes the first found of ~/.bash_profile, ~/.bash_login or 
~/.profile.  None of the last three are found in Knoppix 3.8 so only 
/etc/profile should be executed.

A non-login shell reads and executes /etc/bashrc.bashrc if found _and_ 
reads and executes ~/.bashrc.  Since only .bashrc exists in Knoppix 3.8 
only ~/.bashrc can run.

Curious.
