I'm afraid I am the culprit, or more precisely this commit:
http://github.com/puppetlabs/puppet/commit/b581c2348e784ce5d857a4c1c0686399b87cc13f
Regex matching in puppet has been case sensitive since the first day
(and maybe it was the wrong choice).
As a workaround you can use uppercase in your regexes:
/(Ubuntu|Debian)/
I suggest you to file (several) bug reports about this (one for the case
sensitivity issue, one for the documentation, and one feature for the
uppercase/lowercase functions).
