Digikam 7.2-RC Segfault, no bt

Hello,

I'm running the 7.2-RC appimage on Debian Bullseye, with an external MySQL database. The external MySQL database is hosted on the same machine, and is version 5.6.30-1, installed from the Debian repositories. 

I'm doing a lot of face recognition (200,000+ photos) and am getting intermittent crashes. But it seems that there's no backtrace.

I haven't been able to nail down a specific workflow that is guaranteed to generate a crash yet.

Tasks I'm usually doing when it crashes are: Running "Recognize Faces", Selecting images in the People pages, Accepting or Rejecting selections. Crashes usually happen when there are many tasks in the Active Process list.

For example, if I have selected 100-300 images and click "Confirm that the selected person is shown here", it sometimes crashes while processing them. Or sometimes it crashes when running Recognize Faces. Or when switching to a Person tag with many (1000s) of images.

I have Digikam writing tags to sidecar files.

I ran it inside GDB this last time, and the final few lines were

Digikam::ItemQueryBuilder::buildQueryFromXml: " ( ( (ImageTagProperties.tagid=? OR ImageTagProperties.tagid IN (SELECT id FROM TagsTree WHERE pid=?)) AND ImageTagProperties.property=?  ) OR ( (ImageTagProperties.tagid=? OR ImageTagProperties.tagid IN (SELECT id FROM TagsTree WHERE pid=?)) AND ImageTagProperties.property=?  ) OR ( (ImageTagProperties.tagid=? OR ImageTagProperties.tagid IN (SELECT id FROM TagsTree WHERE pid=?)) AND ImageTagProperties.property=?  ) OR ( (ImageTagProperties.tagid=? OR ImageTagProperties.tagid IN (SELECT id FROM TagsTree WHERE pid=?)) AND ImageTagProperties.property=?  ) ) "

Is there anything else I can do to try to provide something useful in a bug report? Right now it seems far too vague to be helpful in tracking down the problem.

Thanks,
