--- Comment #3 from Juan Lang juan_lang@yahoo.com 2009-08-19 12:31:06 --- Created an attachment (id=23181) --> (http://bugs.winehq.org/attachment.cgi?id=23181) Patch
MSDN states that Annotation may be NULL or empty, and indeed that it's ignored internally:
"Specify a null value or a null-terminated string ("\0") if there is no annotation string.
The annotation string is used by applications for information only. RPC does not use this string to determine which server instance a client communicates with or for enumerating elements in the endpoint-map database."
This patch should fix it. I'll combine it with a test patch once someone confirms that the test passes on Windows. Nevertheless, you might give this another try with the attached patch just to make sure it fixes it for you.
