Rudder

When a deployment fails due to a failing verification of cf-promises, the message should be added to the "details" pop-up.

But sometime, it is not, details contains:

=> Deployment error for process '13' at 2013/04/25 17:28:14
=> Cannot write configuration node
=> Error when preparing rules for agents
=> The generated promises are invalid, cause is: 
Show technical details
Technical details 

And nothing more, each time cause or details are empty.

You can reproduce that bug with 2.5.* policies (so in a Rudder 2.5), whith the "Download a File" directive, and setting both mandatory path to an invalid value (I used "Download a File").
The bug seems to be also in Rudder 2.4.
