Commit 5b7c84066733c5dfb0e4016d939757b38de189e4 ('ipv4: correct IGMP behavior on v3 query during v2-compatibility mode') added yet another case for query parsing, which can result in max_delay = 0. Substitute a value of 1, as in the usual v3 case. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=654876 code added in 2.6.36-rc8.
