[dovceot-2.2.19] doveadm fts expand constantly gives Segfault

[Marcin Mirosław]

Hi!
When I issue:
doveadm fts expand -A body xxx
I'm always getting Segfault. I can't find descrption of this command in
manual, is it possible to add some information to manual?

# gdb -q doveadm

done.
(gdb) set args fts expand -A body XXX
