Hey guys,

Was just grepping through notmuch sources and discovered what I think are memory leaks in notmuch-show.c’s format_headers_sprinter() code.

Internet_address_list_to_string() and g_mime_message_get_date_as_string() return allocated string buffers and not const, so from what I can tell from taking a look at the sprinter-sexp.c’s sexp_string() function, the code leaks the recipients_string as well as the date string.

Attached is a patch which fixes these leaks.

Hope this helps,

Jeff
