Comment 1 Marcel Wiesweg 2012-07-21 12:22:56 UTC 
Shutdown problem, one thread is running while singletons are destroyed.
Is it reproducible under some circumstances? We'd need to know which preview thread is still running.
Comment 2 Marcel Wiesweg 2012-10-03 14:34:30 UTC 
Reiterating comment 1
You will need to help us: Was any tool or activity open and running when you shut down, Fingerprints generator, SlideShow, FaceDetection? Any other active task when you shut down?
Comment 3 caulier.gilles 2015-06-27 13:42:56 UTC 
New digiKam 4.11.0 is available :

Comment 4 caulier.gilles 2015-08-21 07:07:14 UTC 
digiKam 4.12.0 is out :

https://www.digikam.org/node/741

We need a fresh feedback using this release please...
Thanks in advance.
Comment 5 caulier.gilles 2016-07-02 19:44:30 UTC 
With digiKam 5.0.0, this problem is not reproducible.

I close this file now. Re-open it if necessary.
