When Puppet is trying to configure its various files and directories at startup, it now sometimes does not propagate the actual failures it experiences. This makes debugging those failures enfuriating, so this must be fixed.
For instance, people get this failure:
/Users/rick/git/puppet/lib/puppet/util/settings.rb:595:in `use': Could not configure myself; got 3 failure(s) (RuntimeError)
from /Users/rick/git/puppet/lib/puppet/node/catalog.rb:130:in `apply'
from /Users/rick/git/puppet/lib/puppet/util/settings.rb:588:in `use'
from /opt/local/lib/ruby/1.8/sync.rb:229:in `synchronize'
from /Users/rick/git/puppet/lib/puppet/util/settings.rb:568:in `use'
from /Users/rick/git/puppet/bin/puppetmasterd:166
