Quite possible, when I do notmuch show --entire-thread=true --format=mbox path:Mail/~ml/emacs-orgm...@gnu.org/** date 64 bit 32 > /tmp/emo.mbox and open the resulting mbox with mutt, it shows 10199 messages. There is fun to have regarding message ids: 0 grfz@len:/tmp$ grep -c "^Message-ID:[[:space:]]" eom.mbox 8758 0 grfz@len:/tmp$ grep -ci "^Message-ID:[[:space:]]" eom.mbox 10174 I then split the mbox with mutt in a maildir folder. This were 10199 individual files. I then extracted the message ids via formail from this files and piped this through sort -u. These were 10105 message ids. The maildir with the emacs-orgm...@gnu.org emails contained 114563 individual files. I removed every file somewhere containing one of those message ids. Now there were only 102164 individual files in the maildir. And after that I indexed this cleaned up maildir. If somehow this message threading problem affects the indexing it should now index the files without xapian exeption: This is with newest notmuch: 0 grfz@len:/tmp$ /home/grfz/src/notmuch/notmuch --version notmuch 0.24.2+112~g37d1fa5 0 grfz@len:/tmp$ gdb --args /home/grfz/src/notmuch/notmuch new GNU gdb (Debian 7.12-6) 7.12.0.20161007-git Copyright (C) 2016 Free Software Foundation, Inc.
