This is strange. I rerun the self compiled notmuch new on this corpus and it did not throw an exeption, nore did the debian stretch binary. I have no idea why this is different with the first run. On my way reducing the corpus I had an intermediate corpus of ~43000 files on which notmuch new produced a xapian exeption. I kept this corpus but did not include the test results in my email because the later, smaller corpus seemed more interesting. I redid the test on this mid-sized corpus and I got an exeption (again): 0 (master *) grfz@len:~$ 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.
