Hi all

I'm testing dovecot to migrate from a cyrus 2.2 With TB2 if I use "subscribe" dovecot crash but only if I enable a shared namespace. Without explicit namespace or only with private namespace "subscribe" works Is this a problem already fixed in 1.2.10? is it a problem of my configuration? I tried different value for location in shared namespace but without any difference Below some info + gdb backtrace + dovecot -n

Thanks

Dovecot is version 1:1.2.9-1ubuntu2 from ubuntu lucid recompiled for ubuntu hardy on a xen domu amd64, fs is xfs
