This appears to have been related to some non-thread safe code being used inside a some methods being called from QFuture in ctkDICOMIndexer. Moving that code into the database initialization fixed that problem and the crashes have not happened since.

There are still crashes related to this - apparently QSql connections are not usable across threads, so the ctk code will need to be re-worked.

This has been fixed by removing the threading in CTK. See 0002871.
