Well, not exactly.

`mail-header-parse-addresses' is for parsing RFC822bis mail addresses.
"Štěpán Němec <[email-masked]>" is definitely not one of those.

You're probably looking for `mail-header-parse-address-lax':

(mail-header-parse-address-lax "Štěpán Němec <[email-masked]>")
-> ("[email-masked]" . "Štěpán Němec")

This should probably be documented better.
