#33 Getting Code from Vault Failure - and rebuild loop

[bryan_andrews]

I sent this to the group also. I was able to "fix" this for
a while just monkeying with it, but it started back
around 12:15 last night and started filling our devs
inboxes.

Failed to process build 'DotNetNuke.All'. The following
exception
occurred:
System.InvalidOperationException: Specified IComparer
threw an
exception. ---> System.NullReferenceException: Object
reference not set
to an instance of an object.

Object b)

We are using solution tasks, the latest daily build from
nant (which
will run this build file manually), and vault.

I too have been getting this. I had Draco.NET working
well as I was evaluating solutions, then at some point it
just stopped working and started throwing this error.
Since this happened I have been using FinalBuilder2
instead, but I wan to use FB2 for daily build and
Draco.NET for CI. When it works, things are good. :)
