+Hi\r
+\r
+This seems a very definite bug (when testing I managed to archive a\r
+whole chunk of random messages!) \r
+\r
+However, I think I would prefer not to signal an error and just do\r
+nothing. How about making notmuch-tag check for a nil query (and do\r
+nothing it's nil). Then rather than an error n.s.f.s.q.r can just return\r
+nil (this still needs to be special cased as otherwise we get "()" as\r
+the query.\r
+\r
+Doing this would also fix a bug I found (when seeing what we did\r
+elsewhere based on the above) in notmuch-tree: trying to change tags at\r
+the end of the buffer gives an error).\r
+\r
+Best wishes\r
+\r
+Mark\r
