[mu bug] mu 1.12.3 stops indexing mails

[telmich]

Describe the bug

For a few days mu does not index mails anymore. It still displays existing mails, but does not add new ones.

To Reproduce Run mu index either directly from mu4e or from the command line. Result is:

% mu index
indexing maildir /home/nico/Maildir -> store /home/nico/.cache/mu/xapian
- indexing messages; checked: 1592795; updated/new: 25; cleaned-up: 0
(process:277366): mu-CRITICAL **: 17:05:18.485: xapian_try: xapian error 'Attempted to delete or modify an entry in a non-existent posting list for B08'
| indexing messages; checked: 1592795; updated/new: 25; cleaned-up: 7
[17:05] nb3:~% mu --version
version 1.12.3

The Xapian database got corrupted. Not much I can do about that... you can restore things by starting from scratch, with mu init.

@djcb thanks for the quick reply.

Deleting ~/.cache/mu/xapian and restarting with mu init && mu index indeed does fix the error. Wonder how it broke, but probably out of scope for mu.
