System.NullReferenceException in TypeMockStartTask

Hi,

After I had enabled logging in the NAnt TypeMockStartTask, I got a System.NullReferenceException.
Here is the stack trace extracted from the NAnt log file:

Internal Error: System.NullReferenceException
Object reference not set to an instance of an object.

at TypeMock.NAntBuild.TypeMockStartTask.GetTypeMockDir()
at TypeMock.NAntBuild.TypeMockStartTask.b()
at TypeMock.NAntBuild.TypeMockStartTask.ExecuteTask()
at NAnt.Core.Task.Execute()
at NAnt.Core.Target.Execute()
at NAnt.Core.Project.Execute(String targetName, Boolean forceDependencies)
at NAnt.Core.Project.Execute()
at NAnt.Core.Project.Run()

And here is the relevant portion of the NAnt build script:

<typemockstart
    profilerlaunchedfirst="true"
    target="2.0"
    loglevel="9" />

The exception doesn't occur if I also specify a logging output directory, with the logpath attribute.

What could the problem be here?

Kind regards,
/Enrico
