'calibredb add' fails on some books

[Igor]

There's Calibre v2.48.0 setup on FreeBSD 10.2.
I'm adding multiple books with:

# calibredb add --with-library <path_to_library> <path_to_new_books>

There are following errors for some books:

Traceback (most recent call last):

Attach one of these problematic files. It looks like the metadata reader
plugin for them is returning plain dates rather than full datetimes.

[Kovid Goyal (kovid)]

Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.

Please could you add a verbose mode for calibredb?
Currently if there's processing of a folder with a bunch of files then it's complicated to know which file caused the fail.
