This does sound like a legitimate bug. I couldn't see anything wrong
in your configuration. I was going to suggest that it could have to do
with case sensitivity issues, or with the double "**" used in one of
the filters, but those are both wild guesses.
Someone will need to investigate. I am unlikely to be the quickest
about it as I don't have Visual Studio at the moment. The best way to
launch the process it to create an issue in the JIRA instance at
http://jira.public.thoughtworks.org/browse/CCNET
Include as much detail as you can, perhaps by linking to these
messages in the google groups archive.
