For what it's worth, I haven't seen this on any systems I manage when going from 5.0.22-5.0.45, which include permutations of master-slave and master-master.

[CentOS] Problems with mysql multi-master after update.
Hello, after I updated from mysql-5.0.22 CentOS 5.0 to mysqld-5.0.45 in CentOS 5.2, mysql looses master-slave sync after one node reboots. I've noticed that the slave doest not respect the informantion on master.info, instead, it tries to read the informantion from the master server file inc-index.index. Let me give a example, the master is alredy on incremental.06 and the slave in synced, the master.info in the slave server is showing is is reading de incremental.06, but in the master inc-index.index all 6 files are listed, from 1 to 6. The file 1 to 5 were already deleted in a cleaning process as thay were alread synced with the slave. After the reboot, the slave tries to find the file incremental.01 on the master and this causes the problem. In 5.0.22 this would not happen, this does not happen as I have servers running this version and after the reboot, it starts syncing on the right incremental. Any idea?
