+Subject: [PATCH] lib-mail: message_parser_init_from_parts() - Fix crash if
+ MIME boundaries don't end
+
+If the last "boundary--" doens't exist, the parsing assert-crashed at
+deinit. This mainly happened when searching mails.
+
+Fixes:
+Panic: file message-parser.c: line 175 (message_part_finish): assertion failed: (ctx->nested_parts_count > 0)
