rspec + rcov + rails + sequel (false coverage report)

Anyone use rcov (0.9.4) on a rails (2.3.5) app that is using Sequel (3.8.0)? The coverage report is including blank and comment lines as not being executed. It is also including the class definition line as being not executed when the instance and class methods have been executed. I'm not sure if this has to really do with Sequel, because this is also happening to the controller specs. Rspec(1.3.0) was run with rake(0.8.7) like this rake spec:rcov. The report seems to be totally bogus based on blanks and comments being included. I have used these in the past with AR and it worked fine. I just can't believe Sequel would cause these to break.

any ideas?
