Sorry, some Russian words 
[21:37:47] Brett Lawson: Yea, it LOOKS like it could be a .NET bug, but it also could be a bug in the test.
[21:38:32] Brett Lawson: You should debug a little bit to try and identify how its occuring.
[21:39:52] Andrei Baranouski: okay, will post a ticket for now. then I will commit my sdkd fixes and will provide steps to reproduce (command line)
