2859 repository stuck on "getting changesets"

I have a Mercurial project level repo that is pointing to a BitBucket repo.  It's stuck on "getting changesets" and the build won't proceed.  The repo's settings are correct and it validates.  I'm using 2859.  Any ideas what to do?

Hi Sean,

Are there any messages in the event log? Can you enable debug logging on the server, run a build and then send the log file to support@finalbuilder.com? Also some details of your repository settings would be useful to help us to troubleshooot the problem.
