My logs don't go back far enough to say for sure but I think it's
because of this puppy:

ii  flashplugin-downloader:i386           11.1.102.55ubuntu0.11.10.1
             Adobe Flash Player plugin downloader
ii  flashplugin-installer                 11.1.102.55ubuntu0.11.10.1
             Adobe Flash Player plugin installer

I know I installed the latter.  I guess the former got sucked in.

dpkg-query -W -f='${Package} ${Version}\t${Architecture}\n' chromium-browser

chromium-browser 15.0.874.106~r107270-0ubuntu0.11.10.1  amd64

Dunno.  I will try when I get some free-time.

Linux sato 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011

This was originally Natty.  I understand at that time there was no
native 64-bit version of the flash plugin available.  I think there was
a PPA package.  So now I have a ton of 32-bit packages installed:

dpkg -l | grep :i386 | wc -l
124
