Comment 1 Jesper Brovang 2014-09-03 13:40:53 UTC 
The error was caused by "Schema for mediawiki" was empty. It was empty by default, the guide did not mention anything about it and the help text suggested it only be changed if needed.

Anyways empty is not an option, consider some default value, I choose "mediawiki" and/or implement a value = "" not allowed.
Comment 2 Andre Klapper 2014-09-03 14:06:44 UTC 
Thanks for taking the time to report this!

> The error was caused by "Schema for mediawiki" was empty.

Sorry but I don't get that part.

If I get it right, this is basically a request to improve the documentation? 
If so, you are very welcome to edit http://www.mediawiki.org/wiki/Manual:Installing_MediaWiki
Comment 3 Jeff Janes 2014-09-03 15:03:32 UTC 
This is a manifestation of bug 64043.

In 1.22 it used to provide a reasonable default value for this field.
