Insight
It was discovered that the last security update for Ruby on Rails, DSA-2301-1, introduced a regression in the libactionpack-ruby package. For the oldstable distribution (lenny), this problem has been fixed in version 2.1.0-7+lenny2. For the stable distribution (squeeze), this problem has been fixed in version 2.3.5-1.2+squeeze2. We recommend that you upgrade your rails packages.
