Package: dovecot-core
Version: 1:2.3.21.1+dfsg1-1+b2
Severity: normal
Tags: patch

Dear Maintainer,

on debian trixie, the command 'doveadm index -u $USER "*"' frequently crashes 
with the message "Panic: file fts-filter.c: line 137 (fts_filter_filter): 
assertion failed: ((*token)[0] != '\0')" while indexing mailboxes with the 
fts-flatcurve plugin when using the snowball filter.

This bug is fixed in dovecot's git repository : 
https://github.com/dovecot/core/commit/a1c36cc77977685686e829bcb9e9de79df2280ab.diff

Would it be possible to apply this patch to the debian package ?

Thank you.
