Bitten & Trac 0.12

[anonymous]

Hi, I have got an issue with Bitten (from SVN Bitten 0.6dev) & Trac 0.12. Bitten is installed and when I try to add a Build Configuration in the admin panel, I have got the following error :

Trac detected an internal error:

Attribute Error?: 'None Type?' object has no attribute 'get_node'
