Whenever I try to search on my dovecot test install, dovecot dies. It immediately spawns a new process, which the client tries to connect to, and send search commands to, causing that to die, and so forth. This loop means I have to kill either the server or the client.

Running Dovecot 1.0.13 from/on Debian testing, rebuilt with vpopmail support and no other source changes. Vpopmail version is 5.4.25, latest stable. Client is Mulberry 4.0.8, and the crash seems to occur whenever any type of search is performed, be it subject, sender, body etc. Otherwise the server behaves fine.

dovecot -n output:
