I’m stuck with a bug at the moment which is puzzling me. I have a  
layout containing some HTML and a partial (for the navigation) - there  
is nothing else there other than the yield.

1. If the nav is included as a partial I get nothing returned to the  
browser at all (blank page) but everything else appears normal
2. If I remove the partial the page works fine
3. If I put the nav code directly in the template it works fine
4. if I replace the nav code in the partial with a simple string, I get  
a blank page again.

Does anyone have any ideas as to what the problem could be, or know how  
I might debug it?

Found the issue, the partial was in the layouts folder, instead of the  
relevant controller views folder.

However, Rails was throwing a ActionView::MissingTemplate Exception  
which was only visible via the debugger which is probably a bug.
