I couldn't reproduce this. I guess it requires some specific config. Can
you get bt with debug symbols and/or give full doveconf -n output?


I think this probably has something to do with the fact that my  
namespaces were broken after I upgraded.  These namespaces were broken  
because doveconf didn't import my dovecot v1 config correctly.


With this input:

-

namespace private {
  separator = .
  prefix =
  location = maildir:~/Maildir
  inbox = yes
}

namespace public {
  separator = .
  prefix = "#shared."
  location = maildir:~/mboxtesting
}

-

And running: doveconf -n -c dovecot-1.conf > dovecot-2.conf
(as found at http://wiki2.dovecot.org/Upgrading/2.0)

Results in the following:

--

# 2.0.1: dovecot-1.conf
# OS: Linux 2.6.35-ARCH x86_64
namespace {
  location = maildir:~/mboxtesting
  prefix = #shared.
  separator = .
  type = public
}

namespace {
  location = maildir:~/mboxtesting
  prefix = #shared.
  separator = .
  type = public
}

-

And, thus, both namespaces have the same prefix:

* NAMESPACE (("" ".")) NIL (("" "."))

So doveconf wasn't quoting the prefix value correctly in the converted  
output.  Not sure if you want to put a check/warning somewhere if  
namespaces have the same prefixes.

Can verify that disabling acl makes the segfault go away.
