bug in parsing?

[David Belohrad]

Dear all,

recently I got an email from matplotlib list, which fails to parse in
notmuch-saved-search-unread.
It looks like this:

Yest. 21:04 [3/5]   Jesse Rosenthal, Tomi Ollila  [PATCHv2] emacs: derive correct timestamp in FCC unique name (inbox notmuch)
 Yest. 20:58 [1/1]   Allin Cottrell       mouse and update 23.4 -> 24.1 (emacs inbox)
 Yest. 20:56 [3/6]   Milan Kratochvíl, Jaroslav Lukesh, David Obdrzalek, Pavel Kutina  [OT:] Javascript alert jinak (hw inbox)
Error: Unexpected output from notmuch search:
thread:0000000000006a68  Yest. 20:39 [1/1] R. O'Gara; [Matplotlib-users] (no subject) (matplotlib mightread unread)

 Yest. 19:27 [1/2]   Bob Proulx, sariatucla at Safe-mail.net       next-line at window end without recenter (deleted emacs inbox unread)
 Yest. 19:12 [1/12]  Jiří Kučera, hutta.j at seznam.cz, balu at home, Pavel

It seems that the weird characted in sender does it. Should those
characters be somehow escaped?

cheers
