[digiKam-users] Crash when busy processing modified file system

[Dougie Nisbet]

One of the things I like about digiKam is how it deals with external 
changes to files. However, it seems that this is fragile. If I make a 
lot of external changes; e.g. filename renaming, I find DK copes fine. 
But only if I leave it alone for an hour or two. If I try to do pretty 
much anything while it's still busy scratching its head about the 
nonsense I've been up to while it was asleep, I get this sort of thing, 
and it Aborts.

It's not the end of the world. I can wait. But is there anything I can 
tweak? It usually involves lots of 'Datebase is locked' messages before 
it aborts.

This is digikam-6.3.0-x86-64.appimage on Debian.
