I downloaded (from somewhere) FreeBSD i386 LXDE VirtualBox (.ova) image
and after a while figuring out how to get stuff installed I got
notmuch 0.18.1 installed.

In case I create ~/mail/cur, ~/mail/new and ~/mail/tmp directories,
but mail(s) to ~/mail/new and execute notmuch new...

... notmuch coredumps and I get pretty much the same output as the


My guess is that there is a slight error how this part is displayed:

-- I'd day #4 is actually _notmuch_message_remove_term () 

To resolve this further I suggest that SomeOne(tm) (that means you, Simon)
build notmuch like the following:

  make distclean
  CFLAGS='-ggdb -O0' ./configure
  make

(but no make install -- and next)

  rm -rf ~/mail/.notmuch
  gdb ./notmuch
  run new

and capture the gdb backtrace (let's hope Heisenberg does't intrude!)

(remember to have mails in ~/main/new and synchronize_flags in .notmuch-config.
