Virtual folders always empty

[Glenn Golden]

Hello muttkzoids,

First, +1 for a great forking idea, nice combo of two excellent tools.

Having a bit of trouble getting virtual folders to work though.  Attempting
to do <sidebar-open> always results in an empty folder, regardless of the
search term.  With -d3, seeing stuff like this in the debug log (apparent
error noted with "==>")

When notmuch is executed from the commandline with the same query term, it
seems to behave normally.

Version info: mutt-kz 1.5.23.1 obtained via Arch AUR, configured with
--enable-debug, and notmuch 0.20.1.  Muttrc doesn't seem to be implicated,
but for completeness, tried it with the minimal muttrc given here

http://notmuchmail.org/mutttips/

and see the same problem.

Any ideas on how to track this down further?

No progress on problem previously reported. Wondering if problem may be
related to the fact that my existing setup uses MH style mailboxes rather
than Maildir style.

Can anyone confirm that mutt-kz virtual folders work as expected when
using MH style mailboxes?

The maildirs style is required by notmuch support in mutt-kz and if I
 good remember than notmutch also supports maildirs only.

OK, thanks Karel.

Actually, notmuch seems to work ok with MH style folders, at least, I've
never noticed any issue with it. But I don't use of tags though, only plain
text searching, so maybe this is why it seems to work ok for my use case.

The README.notmuch doesn't explicitly state that maildir format is required
(although it does imply it in a few places).  Would you mind if I put in a pull
request on git to add a sentence or two to README.notmuch, so that this
limitation is made explicit?
