GUIMiner "Failed to subscribe" in "Solo" server

[Zrx]

Hi!

I'm trying to use GUIMiner with solo server but I have a problem.
I follow this thread https://bitcointalk.org/index.php?topic=10438

The problem is when I start mining in console show:
2013-04-14 21:32:26: Listener for "Solo": localhost:8332 14/04/2013 21:32:26, Failed to subscribe
2013-04-14 21:32:28: Listener for "Solo": localhost:8332 14/04/2013 21:32:28, IO errors - 1, tolerance 2

I take a screenshot
