On update: Internal error of the underlying BerkeleyDB database

[cluck]

I just updated Debian from bullseye to bookworm and shortly after that (having called the bookworm version of reprepro successfully from my unchanged scripts) I updated just the reprepro package to the Debian experimental version (5.4.2-1). Immediately my scripts triggered the below error during calls to reprepro includedeb. But after a few repetitions of the same command (I tried to bring up a reproducible case) I suddenly found that the error had stopped from appearing (I did not downgrade in the meantime, reprepro: This is reprepro version 5.4.2).

My gut feeling is that we're looking at a "database" update that crashes in between a "transaction" which no ACID properties, thus after each crash the "old" record is gone, but the "new" record never landed in the "database".

BDB0696 Duplicate data items are not supported with sorted data
Internal error of the underlying BerkeleyDB database:
Within references.db subtable references at put: BDB0067 DB_KEYEXIST: Key/data pair already exists

After re-reading Issue #18 I realize that calling reprepro check and reprepro export while preparing the bug report may have been the commands that "fixed" the database instead.
