Validation errors not shown in CLI

[krihal]

When doing a 'validate push' or 'commit' the device might return an error. Now this is what I see in the CLI:

debian@khn-dev[/]# validate push
Transaction 3 failed Unexpected reply from juniper2 in state PUSH-VALIDATE:
debian@khn-dev[/]#

If I look in the backend debug I can see the real error message, this must be shown in the CLI too:
