Well there are mainly two aspects about a corrupted database:
 1. the database files are simply unreadable. This is basically a sqlite issue
and we should not have to worry about it. Anyway it is easy to detect ;)
 2. the datanase is semantically wrong, e.g. diverges from the images. This is
really hard to detect. If the user does not want to store metadata in the
images, there are only heuristics like counting the number of lines in a table
since last shutdown or something like this. But if the db is the only ground
truth, how to check if it is consistent with the image that are otherwise
unknown to the system?
