google-chrome-unstable apparently removes its executable

[Patrick Wiseman <pwiseman@gmail.com>]

Updating two testing systems this morning, I found that my Chrome
suddenly became unable to find any web pages. Attempting to relaunch,
it wasn't there!

'which google-chrome' returned nothing. I tried 'sudo apt-get install
google-chrome-unstable', but it was already installed. Finally, on
both systems, I did 'sudo apt-get install google-chrome-stable' and
now have a working Chrome again.

I guess that's what I get for being willing to live with unstable!
