Since I don’t get your bug tracking system (d’oh ;), here is a bug I encountered with notmuch-mutt using this macro I guess was from the “official” tutorial: # Construct a thread ouf of the marked mail (or something like that, # doesn’t work atm (errors out)) macro index <F9> \ "<enter-command>unset wait_key<enter><pipe-message> \ /usr/bin/notmuch-mutt thread<enter><change-folder-readonly> \ ~/.cache/notmuch/mutt/results/<enter> \ <enter-command>set wait_key<enter>" \ "search and reconstruct owning thread (using notmuch)" I hope this still works, best to put it on one line I guess. Error message: Use of uninitialized value in pattern match (m//) at /usr/bin/notmuch-mutt line 124, <STDIN> line 28. Use of uninitialized value $mid in concatenation (.) or string at /usr/bin/notmuch-mutt line 145, <STDIN> line 28. ~Profpatsch -- Proudly written in Mutt with Vim on Archlinux.
