+hi folks--\r
+\r
+sorry to not have a clearer debugging statement right no (ENOTIME to\r
+generate something nice) but i think notmuch-emacs was failing to render\r
+a thread for me when one of the messages involved was either signed with\r
+or encrypted using an algorithm that gpg didn't know about.\r
+\r
+I ran into this because i'm working on gpg 2.1, which implements some\r
+OpenPGP elliptic curve crypto.\r
+\r
+notmuch really shouldn't just fail to render the entire thread in the\r
+event that it sees an unknown algorithm -- it should just show the\r
+encrypted message and indicate failure to decrypt.\r
+\r
+If i can get more time, i'll try to dig deeper and craft an example\r
+message, and a proper bug report, but if anyone else can do that part,\r
+i'd appreciate it.\r
