Whilst looking at this, I noticed that there are a couple of other bugs open against the package regarding malloc warnings (#496676 and #514028). The issues reported in both bugs are memory corruption warnings, but I do wonder if this isn't another instance of the same issue and improved / increased malloc checks in squeeze have simply altered the manner in which it presents; unfortunately I don't have any suitable hardware available with which to test. The patch in #496676 fixes two occurrences of essentially the same bug, so looks like the better choice of the two. fwiw, Gentoo have a related patch for a memory leak in http://bugs.gentoo.org/attachment.cgi?id=216343&action=view , which again only fixes one of the two incorrectly-sized mallocs.
