I wonder if this bug can be downgraded (or marked squeeze-ignore). The weaknesses of MD5 are well-known, and support for it should be deprecated, but I don't think that needs to be done for squeeze.
Post-squeeze, the solution should fail for md5 signatures by default. It should require an explicit command-line argument like "--md5-ok" for backwards compatibility.
