symfony - upgrade1.2 and Propel 1.3 DSN

Yup, I have been fiddling around with symfony some more!
Since I installed the latest stable build of symfony (1.2.1), I decide to upgrade my projects using:

symfony project:upgrade1.2

The command processed fine but then all hell broke loose so to speak. Basically, the whole project went kaput. So...
I then ran the magic (that is in the non-PHP sense) command:

symfony plugin:publish-assets

Which fixed all my sfGuardPlugin issues!

My next problem was related to propel. I had my databases.yml file configured like so:

all:
  propel:
    class: sfPropelDatabase
    param:
      phptype: mysql
      database: anxcity
      dsn: 'mysql://root@localhost/anxcity' 

I kept getting an Access denied error for user 'ODBC' which was strange since my DSN contained the user: root.

So... I tried the long form of the databases.yml declaration like so:

all:
  propel:
    class: sfPropelDatabase
    param:
      phptype: mysql
      hostspec: localhost
      database: anxcity
      username: root
      port: 3306
      encoding: utf8
      persistent: true

Then the system complained it wasn't receving the DSN string as planned.
So... I just added it:

dsn: mysql:dbname=anxcity;user=root;host=localhost;port=3306

That seems really trivial BUT ... you do need to use the exact string syntax for it to actually work (which is very different to the DSN string in my original configuration file).
And hey presto!

Thoughts?

Edit:
Ah yes, forgot to say I had to rebuild the model too, using:

symfony propel:build-model
