Bug: fatal error with notmuch new, second run starts indexing all over again

[Gregor Zattler <telegraph@gmx.net>]

Dear notmuch developers,

notmuch new fails while indexing my emails and when executed a
second time it obviously starts over again.  This is on a
up-to-date debian stetch with notmuch from git:

0 (master) grfz@len:~/Mail$ notmuch new
Found 940740 total files (that's not much mail).
Error: A Xapian exception occurred. Halting processing.
Processed 659979 total files in 1h 43m 20s (106 files/sec.).
Added 584654 new messages to the database.
Note: A fatal error was encountered: A Xapian exception occurred
1 (master) grfz@len:~/Mail$ notmuch new
Error: A Xapian exception occurred. Halting processing.
Processed 660023 total files in 1h 44m 45s (105 files/sec.).
Added 584698 new messages to the database.
Note: A fatal error was encountered: A Xapian exception occurred
1 (master) grfz@len:~/Mail$ notmuch --version
notmuch 0.24.2+100~gab02265

The resutling xapian databases are not as large as I would
expect (an older xapian database from another config is 11 G
big): 

0 (master) grfz@len:~/Mail$ du -hs .
28G     .
0 (master) grfz@len:~/Mail$ du -hs .notmuch
7,1G    .notmuch

It's now not possible to search with notmuch:
0 (master) grfz@len:~/Mail$ notmuch search date:year..
0 (master) grfz@len:~/Mail$

Any ideas how to proceed in order to get a working notmuch setup?


Ciao, Gregor
