crash during saving

[Vladimir Marek <Vladimir.Marek@Oracle.COM>]

Hi,

I just indexed my mail archive by notmuch and I'm starting to play with
mutt-kz. The biggest stopper right now is that mutt cores when set
already read mail to new (toggle-new in mutt). Once I try to leave the
virtual folder (be it to another folder or because of quitting mutt) it
crashes.

I haven't had the time yet to investigate deeper, so I'll just post
whatever info I have and hope that it will be something obvious for you
:)

It seems that mutt is calling "notmuch_message_maildir_flags_to_tags"
which in turn tries to remove flag "draft" which probably is not present
and thus raises an exception. Does
"notmuch_message_maildir_flags_to_tags" expect the mail to be in certain
state (have certain flags set) or it should not crash no matter which
flags were and are now set?

Now to be fair I have to say that this is on Solaris with handful of
patches applied to make notmuch compilable there by Oracle Studio
compilers. (I'm working on finalizing the patches to have them suitable
for review, which I want to post soon).

Any tips welcome :)

Thank you
