Hi,

I'm using digikam with an external mysql database.
Since a few week, after an upgrade, all my photos and films are missing their date.
EXIF data are still here and correct.

Looking on the web today, it seems this bugs comes from mariadb (and the mysql connector).
In Debian, the mariadb bug is already tracked by #1139473
Upstream, there are:
- for digikam itself: https://bugs.kde.org/show_bug.cgi?id=523446
- for mariadb: https://jira.mariadb.org/projects/CONC/issues/CONC-821?filter=allopenissues

If you know any workaround (downgrading the mysql connector, etc.), I would be pleased to know.

  Regards,
    Vincent
