The first error is enough info:

~DigikamApp has been run, CacheLock is deleted, and the three default 
ThumbnailLoadThread should have been deleted already. The question is: which 
thread is Thread 16? Where is it created? You could add kDebug()<<this to 
constructor and destructor of ThumbnailLoadThread and check when they are 
deleted.
Unfortunately, I dont get the crash currently.
