Yes, this issue was reported here:

        http://issues.apache.org/jira/browse/MUSE-138

We have a fix but have not committed it yet because of this:

        http://marc.theaimsgroup.com/?l=muse-dev&m=116500393904358&w=2

Look for an update on the 6th - we'll have a fix available in the nightly 
build (for 2.1).

thanks,
Dan
