No dice, problem still happens. I'll provide some extra info at the 
bottom of this, everything I can think of that may be of any interest. I 
can get you access to this machine if it comes down to that. Just to 
restate, to test the nightly build I followed this procedure:

Stopped existing dovecot process.
Built dovecot with this: ./configure --sysconfdir=/etc/dovecot 
--with-mysql --with-ioloop=epoll
make install
start dovecot
rm -rf /var/indexes/*
rm -rf /var/mailstore/.../Maildir (for the test account)
send test message
rm -rf /var/mailstore/.../Maildir
send test message (corruption error, temporary failure to postfix, but 
message delivered)

Result is the same every time I repeat that process. So, I already gave 
my configure options (tried without specifying an ioloop, resulting in 
poll being used instead, with no effect). Here is the summary after 
configure runs:

Install prefix ...................... : /usr/local
File offsets ........................ : 64bit
I/O loop method ..................... : epoll
File change notification method ..... : dnotify
Building with SSL support ........... : yes (OpenSSL)
Building with IPv6 support .......... : yes
Building with pop3 server ........... : yes
Building with mail delivery agent  .. : yes
Building with GSSAPI support ........ : no
Building with user database modules . : static prefetch passwd 
passwd-file checkpassword sql (modules)
Building with password lookup modules : passwd passwd-file shadow 
checkpassword sql (modules)
Building with SQL drivers ............: mysql

The machine is an AMD 64 running CentOS 4.4.

And finally, dovecot -n:
