Compare > > https://issues.guix.gnu.org/issue/36207 > > with > > https://debbugs.gnu.org/cgi/bugreport.cgi?bug=36207 I have fixed this bug. See https://git.systemreboot.net/guile-email/commit/?id=ac83c2a00c13702bc365cd0f3074239fa63d743f and https://git.systemreboot.net/guile-email/commit/?id=1f7c45fa0b71bd137e4b661e0d473c3eb9c98f48 guile-email's parse-email and parse-email-body functions now prefer to operate on bytevectors, rather than on strings. Likewise, mbox->emails now returns a list of bytevectors, not a list of strings. I have updated the API documentation at https://guile-email.systemreboot.net/manual/Parsing-e_002dmail.html#Parsing-e_002dmail @Ricardo: I think you are using a git checkout of guile-email for the mumi hosted at issues.guix.info. Could you use the latest guile-email commit on master (specifically, c85e6917ea21631857d93f58e60d910e07317131)? That should fix this bug. No other changes are required in mumi. I will release guile-email 0.2.0 in another week's time. > This reminds me of rjbs's talk, "Email Hates the Living".

In the future, I'll add some of the pathological examples mentioned in this talk as test cases. Also, if you know of any corpus of email parser test cases, please let me know. I will use them to expand guile-email's test suite.
