Formatting and some debug messages.
Formatting and some debug messages.

This file somehow got a bunch of tabs in it.  Secondly, I added
some message to depict data types.  Recently, I've read a lot of
bug reports which say, "this data doesn't load" or some variation,
don't include data, and come with logs with no relevant
information.

With any luck, such logs will be a bit more useful now.
