Upgrade Ubuntu (9.04 to 9.10)

Since last fall I had a terrible experience with upgrading Ubuntu from 9.04 to 9.10 (left my notebook unusable on the road), it was with great trepidation that, all these months later, I considered doing this.  I'd read a piece on "quickly", and tried it on my netbook (which has 9.10), so I wanted to try this for my desktop (particularly, to setup a template for other than bazaar, and other than Launchpad hosting - notably interested in using mercurial, and - because of Guido von Rossum's code review tool - Google Code).

I backed up my user spaces, swallowed hard and went forward.

I'm now running 9.10 on my desk.   There were a few problems, but nothing that apeared to hurt the install.  I also upgraded to the beta NVidia drivers (their performance seemed noticable on ION, so I thought I'd try them here too).

Here's the problems (such as they were) that did show up during the install:

• Notice about ghc6-doc failing to install (documentation for the Haskell compiler - I just removed it for now;
• Old rpm database for installed (?) rpm packages not usable with the new version;  (I just glanced at it - I think it must be empty... I'm not worrying about this)

I have (so far) noticed this:  when trying to bring up nautilus from a terminal window, I'm getting:

(nautilus:9916): Eel-CRITICAL **: eel_preferences_get_boolean: assertion `preferences_is_initialized ()' failed
