Bug#1113998: akonadi-server: If you have more than 1000 mail folders, not all are indexed/visible in kmail

[Johannes Ranke <jranke@uni-bremen.de>]

Package: akonadi-server
Version: 4:24.12.3-1
Severity: important
Tags: upstream

Dear Maintainer,

After upgrading to trixie, I do not see all my kmail folders any more.
In akonadiconsole, the folders missing in kmail are grey and their
content is not shown, although a count is given for the contained items.

This is a known problem [1] and has apparently been fixed upstream [2].

Please backport the fix to trixie, so trixied users can use large collections
of mail folders.

Let me know if I can help or test.

Johannes
