I've just been able to reproduce the problem in latest master, so i am
afraid the answer is no :) This is the beginning of the backtrace I get
when A T in a nnselect buffer (with notmuch as its engine):

So, when we invoke A T, somewhere in the twisted maze we're trying to
construct an invalid query string... maybe that rings a bell to someone?

Curiously (or not), if i A W on the article instead, that works, and an
A T there (its original group) works fine too.
