It seems like there has been an incompatible schema change made to the toaster database somewhere between the released daisy branch and the current master.

Attempting to perform toaster builds with Daisy clients against the current master results in numerous errors; see the output from the 'toaster_ui.log' below.

We are using a 'production' setup where we run the toaster server on a separate machine using a mysql database.

Steps to reproduce:

Pull the poky master (this was reproduced with commit:a5531a2b8983318b99c119a87b78a92cf84160b8), and then:

mysql> drop database toaster;
mysql> create database toaster;

python bitbake/lib/toaster/manage.py syncdb
python bitbake/lib/toaster/manage.py migrate orm
python bitbake/lib/toaster/manage.py migrate bldcontrol

(The wiki page does not mention this last one but the ‘syncdb' command
mentions that this one is also 'not synced’.)

To start the master, I have written a short upstart script that does the
following:

DATABASE_URL='mysql://user:pass@node:3306/toaster' python
$BASEDIR/bitbake/lib/toaster/manage.py runserver

After running this command, I verified that the server is up and running (I see the "This is Toaster" page).

Then try to run a client build based on the released 1.6 (client:5306aaab07a7a9b3b0c7e8008dabbd2e89daec28) Poky:

$ bitbake --postread conf/toaster.conf --server-only -t xmlrpc -B localhost:0 && export BBSERVER=localhost:-1
$ nohup bitbake --observe-only -u toasterui &
$ bitbake <some-image>

Expected Result: 

+ A build would be recorded in the remote toaster instance

Actual result:

+ No build is recorded
+ Numerous errors are posted to the toaster log on the client, see below for examples:
