Description

https://github.com/LMDB/lmdb/commit/1ffe472a080fcd3c7dab6e352848703ad7adbe14 is an upstream fix for the LMDB database that fixes the most common crash in Baloo: https://bugs.kde.org/show_bug.cgi?id=389848 (currently at 42 duplicates).

This fix is in LMDB 0.9.23. Unfortunately, Disco currently only has 0.9.22 (see https://packages.ubuntu.com/disco/allpackages).

If we can't get Disco to include 0.9.23, we chould consider backporting https://github.com/LMDB/lmdb/commit/1ffe472a080fcd3c7dab6e352848703ad7adbe14.

And we might want to consider doing this for Bionic too, regardless.

Please report a bug against the package in launchpad. Then me or Simon can look at this.

The built lib liblmdb0 has symbols file, so may need to look at what happens there (if anything).

$ reverse-depends liblmdb0

Fixed for Disco

I would argue not all done. As per https://bugs.launchpad.net/ubuntu/+source/lmdb/+bug/1812122 the uploads for Bionic and Cosmic are still only in the proposed pocket, and require testing/verification (confirmed on the bug) to allow the fixed packages to reach the updates pocket where they ship to normal users.
