Description:
set up : master db where all the write happens
         federated db which is a connection to the slave db
         slave db where replication is configured as slave to the master using the fedrated engine

Problem : although data is properly populated in all the tables of the master db ,In the slave dbs some columns happen to be null these columns have datatype as varchar.

This problem does not occur when replication is done without a federated db connection

replication is done form the mysql client using the start slave command .
the start position and the end master currnt postion are changed everytime a start slave is done          

How to repeat:
create a replication set up 
master myisam engine
replication through federated db
slave innodb engine

run replication continuously using the start slave command changing the start position.

Thank you for the report.

But version 5.0.45 is old and many bugs were fixed since. Please try current version 5.0.90 and inform us if problem still exists.
