New crash information added by DrKonqi
kmail (5.10.1) using Qt 5.11.3
- What I was doing when the application crashed:
Same thing as before: KMail just sitting idly. The improved backtrace suggests it's related to an indexing job happening sometime in the background.
-- Backtrace (Reduced):

The Xapian documentation on DatabaseModifiedError: https://getting-started-with-xapian.readthedocs.io/en/latest/practical_example/searching/database_modified.html So that makes it sound like a pretty straightforward fix...? See also the location where the exception is thrown from Xapian:

isn't reported by drkonqi, so here it is for completeness sake: The revision being read has been discarded - you should call Xapian::Database::reopen() and retry the operation *** Bug 404194 has been

Git commit ff6cdf57350228004ad431b7b0d98fa8d3f7d120 by Ahmad Samir. Committed on 18/08/2020 at 17:41. Pushed by dvratil into branch 'master'. Fix crash by handling exceptions thrown by GlassTable::set_overwritten Xapian::Enquire::get_mset ultimately calls GlassTable::block_to_cursor, which could throw Xapian::DatabaseModifiedError if the database has been modified/deviated too much since it was opened for searching; handle that case by trying to call reopen on the database (as per the upstream error message[1]), then query it again, if that fails just return. Also handle one other exception, Xapian::DatabaseCorruptError; this has been reported in [2]. Use QByteArray::toStdString when calling the Xapian::Database ctor.
