Redmine

The following exception
`block in non_options': file not found: _____ (ArgumentError)
is thrown for every rake task runned in a test environment.

There is a bug for this in rake https://github.com/jimweirich/rake/issues/51
Possible workarounds:

• remove "shoulda"
• add "test-unit" (as marutosi did https://github.com/Vanuan/redmine/commit/db12487dddf5cc73e1266447e9d23676d187af5d)
