syncrepl and schema replication crashes

[manu@netbsd.org (Emmanuel Dreyfus)]

I just upgraded to 2.4.8, and I experience a stability problem with
synrepl and schema replication.

My replicas get cn=schema,cn=config through syncrepl. If the master is
restarted, the replicas tend to crash (not always, but very frequently).
The problem disapear if I don't replicate cn=schema,cn=config.

Below is a log of what happens at master restaty time, and the backtrace
I collected in GDB. Any suggestion of what should I try next?
